+Contributions to pyqtgraph are welcome!
+
+Please use the following guidelines when preparing changes:
+
+* The preferred method for submitting changes is by github pull request
+ against the "develop" branch. If this is inconvenient, don't hesitate to
+ submit by other means.
+
+* Pull requests should include only a focused and related set of changes.
+ Mixed features and unrelated changes (such as .gitignore) will usually be
+ rejected.
+
+* For major changes, it is recommended to discuss your plans on the mailing
+ list or in a github issue before putting in too much effort.
+
+ * Along these lines, please note that pyqtgraph.opengl will be deprecated
+ soon and replaced with VisPy.
+
+* Writing proper documentation and unit tests is highly encouraged. PyQtGraph
+ uses nose / py.test style testing, so tests should usually be included in a
+ tests/ directory adjacent to the relevant code.
+
+* Documentation is generated with sphinx; please check that docstring changes
+ compile correctly.
+
+* Style guidelines:
+
+ * PyQtGraph prefers PEP8 for most style issues, but this is not enforced
+ rigorously as long as the code is clean and readable.
+
+ * Use `python setup.py style` to see whether your code follows
+ the mandatory style guidelines checked by flake8.
+
+ * Exception 1: All variable names should use camelCase rather than
+ underscore_separation. This is done for consistency with Qt
+
+ * Exception 2: Function docstrings use ReStructuredText tables for
+ describing arguments:
+
+ ```
+ ============== ========================================================
+ **Arguments:**
+ argName1 (type) Description of argument
+ argName2 (type) Description of argument. Longer descriptions must
+ be wrapped within the column guidelines defined by the
+ "====" header and footer.
+ ============== ========================================================
+ ```
+
+ QObject subclasses that implement new signals should also describe
+ these in a similar table.
+
+* Setting up a test environment.
+
+ Tests for a module should ideally cover all code in that module,
+ i.e., statement coverage should be at 100%.
+
+ To measure the test coverage, install py.test, pytest-cov and pytest-xdist.
+ Then run 'py.test --cov -n 4' to run the test suite with coverage on 4 cores.

+
+Installation Methods
+--------------------
+
+ * To use with a specific project, simply copy the pyqtgraph subdirectory
+ anywhere that is importable from your project. PyQtGraph may also be
+ used as a git subtree by cloning the git-core repository from github.
+ * To install system-wide from source distribution:
+ `$ python setup.py install`
+ * For installation packages, see the website (pyqtgraph.org)
+ * On debian-like systems, pyqtgraph requires the following packages:
+ python-numpy, python-qt4 | python-pyside
+ For 3D support: python-opengl, python-qt4-gl | python-pyside.qtopengl
+
+Documentation
+-------------
+
+There are many examples; run `python -m pyqtgraph.examples` for a menu.
+
+Some (incomplete) documentation exists at this time.
+ * Easiest place to get documentation is at <http://www.pyqtgraph.org/documentation>
+ * If you acquired this code as a .tar.gz file from the website, then you can also look in
+ doc/html.
+ * If you acquired this code via GitHub, then you can build the documentation using sphinx.
+ From the documentation directory, run:
+ `$ make html`
+
+Please feel free to pester Luke or post to the forum if you need a specific
+ section of documentation to be expanded.

+3D Graphics
+===========
+
+PyQtGraph uses OpenGL to provide a 3D scenegraph system. This system is functional but still early in development.
+Current capabilities include:
+
+* 3D view widget with zoom/rotate controls (mouse drag and wheel)
+* Scenegraph allowing items to be added/removed from scene with per-item transformations and parent/child relationships.
+* Triangular meshes
+* Basic mesh computation functions: isosurfaces, per-vertex normals
+* Volumetric rendering item
+* Grid/axis items
+
+See the :doc:`API Reference </3dgraphics/index>` and the Volumetric (GLVolumeItem.py) and Isosurface (GLMeshItem.py) examples for more information.
+
+Basic usage example::
+
+ ## build a QApplication before building other widgets
+ import pyqtgraph as pg
+ pg.mkQApp()
+
+ ## make a widget for displaying 3D objects
+ import pyqtgraph.opengl as gl
+ view = gl.GLViewWidget()
+ view.show()
+
+ ## create three grids, add each to the view
+ xgrid = gl.GLGridItem()
+ ygrid = gl.GLGridItem()
+ zgrid = gl.GLGridItem()
+ view.addItem(xgrid)
+ view.addItem(ygrid)
+ view.addItem(zgrid)
+
+ ## rotate x and y grids to face the correct direction
+ xgrid.rotate(90, 0, 1, 0)
+ ygrid.rotate(90, 1, 0, 0)
+
+ ## scale each grid differently
+ xgrid.scale(0.2, 0.1, 0.1)
+ ygrid.scale(0.2, 0.1, 0.1)
+ zgrid.scale(0.1, 0.2, 0.1)

+PyQtGraph's 3D Graphics System
+==============================
+
+The 3D graphics system in pyqtgraph is composed of a :class:`view widget <pyqtgraph.opengl.GLViewWidget>` and
+several graphics items (all subclasses of :class:`GLGraphicsItem <pyqtgraph.opengl.GLGraphicsItem>`) which
+can be added to a view widget.
+
+**Note 1:** pyqtgraph.opengl is based on the deprecated OpenGL fixed-function pipeline. Although it is
+currently a functioning system, it is likely to be superceded in the future by `VisPy <http://vispy.org>`_.
+
+**Note 2:** use of this system requires python-opengl bindings. Linux users should install the python-opengl
+packages from their distribution. Windows/OSX users can download from `<http://pyopengl.sourceforge.net>`_.

+Exporting
+=========
+
+PyQtGraph provides a variety of export formats for all 2D graphics. For 3D graphics, see `Exporting 3D Graphics`_ below.
+
+Exporting from the GUI
+----------------------
+
+Any 2D graphics can be exported by right-clicking on the graphic, then selecting 'export' from the context menu.
+This will display the export dialog in which the user must:
+
+#. Select an item (or the entire scene) to export. Selecting an item will cause the item to be hilighted in the original
+ graphic window (but this hilight will not be displayed in the exported file).
+#. Select an export format.
+#. Change any desired export options.
+#. Click the 'export' button.
+
+Export Formats
+--------------
+
+* Image - PNG is the default format. The exact set of image formats supported will depend on your Qt libraries. However,
+ common formats such as PNG, JPG, and TIFF are almost always available.
+* SVG - Graphics exported as SVG are targeted to work as well as possible with both Inkscape and
+ Adobe Illustrator. For high quality SVG export, please use PyQtGraph version 0.9.3 or later.
+ This is the preferred method for generating publication graphics from PyQtGraph.
+* CSV - Exports plotted data as CSV. This exporter _only_ works if a PlotItem is selected for export.
+* Matplotlib - This exporter opens a new window and attempts to re-plot the
+ data using matplotlib (if available). Note that some graphic features are either not implemented
+ for this exporter or not available in matplotlib. This exporter _only_ works if a PlotItem is selected
+ for export.
+* Printer - Exports to the operating system's printing service. This exporter is provided for completeness,
+ but is not well supported due to problems with Qt's printing system.
+
+
+
+Exporting from the API
+----------------------
+
+To export a file programatically, follow this example::
+
+ import pyqtgraph as pg
+ import pyqtgraph.exporters
+
+ # generate something to export
+ plt = pg.plot([1,5,2,4,3])
+
+ # create an exporter instance, as an argument give it
+ # the item you wish to export
+ exporter = pg.exporters.ImageExporter(plt.plotItem)
+
+ # set export parameters if needed
+ exporter.parameters()['width'] = 100 # (note this also affects height parameter)
+
+ # save to file
+ exporter.export('fileName.png')
+
+
+Exporting 3D Graphics
+---------------------
+
+The exporting functionality described above is not yet available for 3D graphics. However, it is possible to
+generate an image from a GLViewWidget by using QGLWidget.grabFrameBuffer or QGLWidget.renderPixmap::
+
+ glview.grabFrameBuffer().save('fileName.png')
+
+See the Qt documentation for more information.

+Visual Programming with Flowcharts
+==================================
+
+PyQtGraph's flowcharts provide a visual programming environment similar in concept to LabView--functional modules are added to a flowchart and connected by wires to define a more complex and arbitrarily configurable algorithm. A small number of predefined modules (called Nodes) are included with pyqtgraph, but most flowchart developers will want to define their own library of Nodes. At their core, the Nodes are little more than 1) a python function 2) a list of input/output terminals, and 3) an optional widget providing a control panel for the Node. Nodes may transmit/receive any type of Python object via their terminals.
+
+One major limitation of flowcharts is that there is no mechanism for looping within a flowchart. (however individual Nodes may contain loops (they may contain any Python code at all), and an entire flowchart may be executed from within a loop).
+
+There are two distinct modes of executing the code in a flowchart:
+
+1. Provide data to the input terminals of the flowchart. This method is slower and will provide a graphical representation of the data as it passes through the flowchart. This is useful for debugging as it allows the user to inspect the data at each terminal and see where exceptions occurred within the flowchart.
+2. Call :func:`Flowchart.process() <pyqtgraph.flowchart.Flowchart.process>`. This method does not update the displayed state of the flowchart and only retains the state of each terminal as long as it is needed. Additionally, Nodes which do not contribute to the output values of the flowchart (such as plotting nodes) are ignored. This mode allows for faster processing of large data sets and avoids memory issues which can occur if too much data is present in the flowchart at once (e.g., when processing image data through several stages).
+
+See the flowchart example for more information.
+
+API Reference:
+
+.. toctree::
+ :maxdepth: 2
+
+ flowchart
+ node
+ terminal
+
+Basic Use
+---------
+
+Flowcharts are most useful in situations where you have a processing stage in your application that you would like to be arbitrarily configurable by the user. Rather than giving a pre-defined algorithm with parameters for the user to tweak, you supply a set of pre-defined functions and allow the user to arrange and connect these functions how they like. A very common example is the use of filter networks in audio / video processing applications.
+
+To begin, you must decide what the input and output variables will be for your flowchart. Create a flowchart with one terminal defined for each variable::
+
+ ## This example creates just a single input and a single output.
+ ## Flowcharts may define any number of terminals, though.
+ from pyqtgraph.flowchart import Flowchart
+ fc = Flowchart(terminals={
+ 'nameOfInputTerminal': {'io': 'in'},
+ 'nameOfOutputTerminal': {'io': 'out'}
+ })
+
+In the example above, each terminal is defined by a dictionary of options which define the behavior of that terminal (see :func:`Terminal.__init__() <pyqtgraph.flowchart.Terminal.__init__>` for more information and options). Note that Terminals are not typed; any python object may be passed from one Terminal to another.
+
+Once the flowchart is created, add its control widget to your application::
+
+ ctrl = fc.ctrlWidget()
+ myLayout.addWidget(ctrl) ## read Qt docs on QWidget and layouts for more information
+
+The control widget provides several features:
+
+* Displays a list of all nodes in the flowchart containing the control widget for
+ each node.
+* Provides access to the flowchart design window via the 'flowchart' button
+* Interface for saving / restoring flowcharts to disk.
+
+At this point your user has the ability to generate flowcharts based on the built-in node library. It is recommended to provide a default set of flowcharts for your users to build from.
+
+All that remains is to process data through the flowchart. As noted above, there are two ways to do this:
+
+.. _processing methods:
+
+1. Set the values of input terminals with :func:`Flowchart.setInput() <pyqtgraph.flowchart.Flowchart.setInput>`, then read the values of output terminals with :func:`Flowchart.output() <pyqtgraph.flowchart.Flowchart.output>`::
+
+ fc.setInput(nameOfInputTerminal=newValue)
+ output = fc.output() # returns {terminalName:value}
+
+ This method updates all of the values displayed in the flowchart design window, allowing the user to inspect values at all terminals in the flowchart and indicating the location of errors that occurred during processing.
+2. Call :func:`Flowchart.process() <pyqtgraph.flowchart.Flowchart.process>`::
+
+ output = fc.process(nameOfInputTerminal=newValue)
+
+ This method processes data without updating any of the displayed terminal values. Additionally, all :func:`Node.process() <pyqtgraph.flowchart.Node.process>` methods are called with display=False to request that they not invoke any custom display code. This allows data to be processed both more quickly and with a smaller memory footprint, but errors that occur during Flowchart.process() will be more difficult for the user to diagnose. It is thus recommended to use this method for batch processing through flowcharts that have already been tested and debugged with method 1.
+
+Implementing Custom Nodes
+-------------------------
+
+PyQtGraph includes a small library of built-in flowchart nodes. This library is intended to cover some of the most commonly-used functions as well as provide examples for some more exotic Node types. Most applications that use the flowchart system will find the built-in library insufficient and will thus need to implement custom Node classes.
+
+A node subclass implements at least:
+
+1) A list of input / output terminals and their properties
+2) A :func:`process() <pyqtgraph.flowchart.Node.process>` function which takes the names of input terminals as keyword arguments and returns a dict with the names of output terminals as keys.
+
+Optionally, a Node subclass can implement the :func:`ctrlWidget() <pyqtgraph.flowchart.Node.ctrlWidget>` method, which must return a QWidget (usually containing other widgets) that will be displayed in the flowchart control panel. A minimal Node subclass looks like::
+
+ class SpecialFunctionNode(Node):
+ """SpecialFunction: short description
+
+ This description will appear in the flowchart design window when the user
+ selects a node of this type.
+ """
+ nodeName = 'SpecialFunction' # Node type name that will appear to the user.
+
+ def __init__(self, name): # all Nodes are provided a unique name when they
+ # are created.
+ Node.__init__(self, name, terminals={ # Initialize with a dict
+ # describing the I/O terminals
+ # on this Node.
+ 'inputTerminalName': {'io': 'in'},
+ 'anotherInputTerminal': {'io': 'in'},
+ 'outputTerminalName': {'io': 'out'},
+ })
+
+ def process(self, **kwds):
+ # kwds will have one keyword argument per input terminal.
+
+ return {'outputTerminalName': result}
+
+ def ctrlWidget(self): # this method is optional
+ return someQWidget
+
+Some nodes implement fairly complex control widgets, but most nodes follow a simple form-like pattern: a list of parameter names and a single value (represented as spin box, check box, etc..) for each parameter. To make this easier, the :class:`~pyqtgraph.flowchart.library.common.CtrlNode` subclass allows you to instead define a simple data structure that CtrlNode will use to automatically generate the control widget. This is used in many of the built-in library nodes (especially the filters).
+
+There are many other optional parameters for nodes and terminals -- whether the user is allowed to add/remove/rename terminals, whether one terminal may be connected to many others or just one, etc. See the documentation on the :class:`~pyqtgraph.flowchart.Node` and :class:`~pyqtgraph.flowchart.Terminal` classes for more details.
+
+After implementing a new Node subclass, you will most likely want to register the class so that it appears in the menu of Nodes the user can select from::
+
+ import pyqtgraph.flowchart.library as fclib
+ fclib.registerNodeType(SpecialFunctionNode, [('Category', 'Sub-Category')])
+
+The second argument to registerNodeType is a list of tuples, with each tuple describing a menu location in which SpecialFunctionNode should appear.
+
+See the FlowchartCustomNode example for more information.
+
+
+Debugging Custom Nodes
+^^^^^^^^^^^^^^^^^^^^^^
+
+When designing flowcharts or custom Nodes, it is important to set the input of the flowchart with data that at least has the same types and structure as the data you intend to process (see `processing methods`_ #1 above). When you use :func:`Flowchart.setInput() <pyqtgraph.flowchart.Flowchart.setInput>`, the flowchart displays visual feedback in its design window that can tell you what data is present at any terminal and whether there were errors in processing. Nodes that generated errors are displayed with a red border. If you select a Node, its input and output values will be displayed as well as the exception that occurred while the node was processing, if any.
+
+
+Using Nodes Without Flowcharts
+------------------------------
+
+Flowchart Nodes implement a very useful generalization in data processing by combining a function with a GUI for configuring that function. This generalization is useful even outside the context of a flowchart. For example::
+
+ ## We defined a useful filter Node for use in flowcharts, but would like to
+ ## re-use its processing code and GUI without having a flowchart present.
+ filterNode = MyFilterNode("filterNodeName")
+
+ ## get the Node's control widget and place it inside the main window
+ filterCtrl = filterNode.ctrlWidget()
+ someLayout.addWidget(filterCtrl)
+
+ ## later on, process data through the node
+ filteredData = filterNode.process(inputTerminal=rawData)
+

+Color, Pen, and Brush Functions
+-------------------------------
+
+Qt uses the classes QColor, QPen, and QBrush to determine how to draw lines and fill shapes. These classes are highly capable but somewhat awkward to use. PyQtGraph offers the functions :func:`~pyqtgraph.mkColor`, :func:`~pyqtgraph.mkPen`, and :func:`~pyqtgraph.mkBrush` to simplify the process of creating these classes. In most cases, however, it will be unnecessary to call these functions directly--any function or method that accepts *pen* or *brush* arguments will make use of these functions for you. For example, the following three lines all have the same effect::
+
+ pg.plot(xdata, ydata, pen='r')
+ pg.plot(xdata, ydata, pen=pg.mkPen('r'))
+ pg.plot(xdata, ydata, pen=QPen(QColor(255, 0, 0)))

+PyQtGraph's Graphics Items
+==========================
+
+Since pyqtgraph relies on Qt's GraphicsView framework, most of its graphics functionality is implemented as QGraphicsItem subclasses. This has two important consequences: 1) virtually anything you want to draw can be easily accomplished using the functionality provided by Qt. 2) Many of pyqtgraph's GraphicsItem classes can be used in any normal QGraphicsScene.

+How to use pyqtgraph
+====================
+
+There are a few suggested ways to use pyqtgraph:
+
+* From the interactive shell (python -i, ipython, etc)
+* Displaying pop-up windows from an application
+* Embedding widgets in a PyQt application
+
+
+
+Command-line use
+----------------
+
+PyQtGraph makes it very easy to visualize data from the command line. Observe::
+
+ import pyqtgraph as pg
+ pg.plot(data) # data can be a list of values or a numpy array
+
+The example above would open a window displaying a line plot of the data given. The call to :func:`pg.plot <pyqtgraph.plot>` returns a handle to the :class:`plot widget <pyqtgraph.PlotWidget>` that is created, allowing more data to be added to the same window. **Note:** interactive plotting from the python prompt is only available with PyQt; PySide does not run the Qt event loop while the interactive prompt is running. If you wish to use pyqtgraph interactively with PySide, see the 'console' :ref:`example <examples>`.
+
+Further examples::
+
+ pw = pg.plot(xVals, yVals, pen='r') # plot x vs y in red
+ pw.plot(xVals, yVals2, pen='b')
+
+ win = pg.GraphicsWindow() # Automatically generates grids with multiple items
+ win.addPlot(data1, row=0, col=0)
+ win.addPlot(data2, row=0, col=1)
+ win.addPlot(data3, row=1, col=0, colspan=2)
+
+ pg.show(imageData) # imageData must be a numpy array with 2 to 4 dimensions
+
+We're only scratching the surface here--these functions accept many different data formats and options for customizing the appearance of your data.
+
+
+Displaying windows from within an application
+---------------------------------------------
+
+While I consider this approach somewhat lazy, it is often the case that 'lazy' is indistinguishable from 'highly efficient'. The approach here is simply to use the very same functions that would be used on the command line, but from within an existing application. I often use this when I simply want to get a immediate feedback about the state of data in my application without taking the time to build a user interface for it.
+
+
+Embedding widgets inside PyQt applications
+------------------------------------------
+
+For the serious application developer, all of the functionality in pyqtgraph is available via :ref:`widgets <api_widgets>` that can be embedded just like any other Qt widgets. Most importantly, see: :class:`PlotWidget <pyqtgraph.PlotWidget>`, :class:`ImageView <pyqtgraph.ImageView>`, :class:`GraphicsLayoutWidget <pyqtgraph.GraphicsLayoutWidget>`, and :class:`GraphicsView <pyqtgraph.GraphicsView>`. PyQtGraph's widgets can be included in Designer's ui files via the "Promote To..." functionality:
+
+#. In Designer, create a QGraphicsView widget ("Graphics View" under the "Display Widgets" category).
+#. Right-click on the QGraphicsView and select "Promote To...".
+#. Under "Promoted class name", enter the class name you wish to use ("PlotWidget", "GraphicsLayoutWidget", etc).
+#. Under "Header file", enter "pyqtgraph".
+#. Click "Add", then click "Promote".
+
+See the designer documentation for more information on promoting widgets. The "VideoSpeedTest" and "ScatterPlotSpeedTest" examples both demonstrate the use of .ui files that are compiled to .py modules using pyuic4 or pyside-uic. The "designerExample" example demonstrates dynamically generating python classes from .ui files (no pyuic4 / pyside-uic needed).
+
+
+PyQt and PySide
+---------------
+
+PyQtGraph supports two popular python wrappers for the Qt library: PyQt and PySide. Both packages provide nearly identical
+APIs and functionality, but for various reasons (discussed elsewhere) you may prefer to use one package or the other. When
+pyqtgraph is first imported, it automatically determines which library to use by making the fillowing checks:
+
+#. If PyQt4 is already imported, use that
+#. Else, if PySide is already imported, use that
+#. Else, attempt to import PyQt4
+#. If that import fails, attempt to import PySide.
+
+If you have both libraries installed on your system and you wish to force pyqtgraph to use one or the other, simply
+make sure it is imported before pyqtgraph::
+
+ import PySide ## this will force pyqtgraph to use PySide instead of PyQt4
+ import pyqtgraph as pg
+
+
+Embedding PyQtGraph as a sub-package of a larger project
+--------------------------------------------------------
+
+When writing applications or python packages that make use of pyqtgraph, it is most common to install pyqtgraph system-wide (or within a virtualenv) and simply call `import pyqtgraph` from within your application. The main benefit to this is that pyqtgraph is configured independently of your application and thus you (or your users) are free to install newer versions of pyqtgraph without changing anything in your application. This is standard practice when developing with python.
+
+However, it is also often the case, especially for scientific applications, that software is written for a very specific purpose and then archived. If we want to ensure that the software will still work ten years later, then it is preferrable to tie the application to a very specific version of pyqtgraph and *avoid* importing the system-installed version of pyqtgraph, which may be much newer (and potentially incompatible). This is especially the case when the application requires site-specific modifications to the pyqtgraph package which may not be present in the main releases.
+
+PyQtGraph facilitates this usage through two mechanisms. First, all internal import statements in pyqtgraph are relative, which allows the package to be renamed or used as a sub-package without any naming conflicts with other versions of pyqtgraph on the system (that is, pyqtgraph never refers to itself internally as 'pyqtgraph'). Second, a git subtree repository is available at https://github.com/pyqtgraph/pyqtgraph-core.git that contains only the 'pyqtgraph/' subtree, allowing the code to be cloned directly as a subtree of the application which uses it.
+
+The basic approach is to clone the repository into the appropriate location in your package. When you import pyqtgraph from within your package, be sure to use the full name to avoid importing any system-installed pyqtgraph packages. For example, imagine a simple project has the following structure::
+
+ my_project/
+ __init__.py
+ plotting.py
+ """Plotting functions used by this package"""
+ import pyqtgraph as pg
+ def my_plot_function(*data):
+ pg.plot(*data)
+
+To embed a specific version of pyqtgraph, we would clone the pyqtgraph-core repository inside the project::
+
+ my_project$ git clone https://github.com/pyqtgraph/pyqtgraph-core.git
+
+Then adjust the import statements accordingly::
+
+ my_project/
+ __init__.py
+ pyqtgraph/
+ plotting.py
+ """Plotting functions used by this package"""
+ import my_project.pyqtgraph as pg # be sure to use the local subpackage
+ # rather than any globally-installed
+ # versions.
+ def my_plot_function(*data):
+ pg.plot(*data)
+
+Use ``git checkout pyqtgraph-core-x.x.x`` to select a specific version of the repository, or use ``git pull`` to pull pyqtgraph updates from upstream (see the git documentation for more information).
+
+For projects that already use git for code control, it is also possible to include pyqtgraph as a git subtree within your own repository. The major advantage to this approach is that, in addition to being able to pull pyqtgraph updates from the upstream repository, it is also possible to commit your local pyqtgraph changes into the project repository and push those changes upstream::
+
+ my_project$ git remote add pyqtgraph-core https://github.com/pyqtgraph/pyqtgraph-core.git
+ my_project$ git fetch pyqtgraph-core
+ my_project$ git merge -s ours --no-commit pyqtgraph-core/core
+ my_project$ mkdir pyqtgraph
+ my_project$ git read-tree -u --prefix=pyqtgraph/ pyqtgraph-core/core
+ my_project$ git commit -m "Added pyqtgraph to project repository"
+
+See the ``git subtree`` documentation for more information.

+Displaying images and video
+===========================
+
+PyQtGraph displays 2D numpy arrays as images and provides tools for determining how to translate between the numpy data type and RGB values on the screen. If you want to display data from common image and video file formats, you will need to load the data first using another library (PIL works well for images and built-in numpy conversion).
+
+The easiest way to display 2D or 3D data is using the :func:`pyqtgraph.image` function::
+
+ import pyqtgraph as pg
+ pg.image(imageData)
+
+This function will accept any floating-point or integer data types and displays a single :class:`~pyqtgraph.ImageView` widget containing your data. This widget includes controls for determining how the image data will be converted to 32-bit RGBa values. Conversion happens in two steps (both are optional):
+
+1. Scale and offset the data (by selecting the dark/light levels on the displayed histogram)
+2. Convert the data to color using a lookup table (determined by the colors shown in the gradient editor)
+
+If the data is 3D (time, x, y), then a time axis will be shown with a slider that can set the currently displayed frame. (if the axes in your data are ordered differently, use numpy.transpose to rearrange them)
+
+There are a few other methods for displaying images as well:
+
+* The :class:`~pyqtgraph.ImageView` class can also be instantiated directly and embedded in Qt applications.
+* Instances of :class:`~pyqtgraph.ImageItem` can be used inside a :class:`ViewBox <pyqtgraph.ViewBox>` or :class:`GraphicsView <pyqtgraph.GraphicsView>`.
+* For higher performance, use :class:`~pyqtgraph.RawImageWidget`.
+
+Any of these classes are acceptable for displaying video by calling setImage() to display a new frame. To increase performance, the image processing system uses scipy.weave to produce compiled libraries. If your computer has a compiler available, weave will automatically attempt to build the libraries it needs on demand. If this fails, then the slower pure-python methods will be used instead.
+
+For more information, see the classes listed above and the 'VideoSpeedTest', 'ImageItem', 'ImageView', and 'HistogramLUT' :ref:`examples`.

+Installation
+============
+
+PyQtGraph does not really require any installation scripts. All that is needed is for the pyqtgraph folder to be placed someplace importable. Most people will prefer to simply place this folder within a larger project folder. If you want to make pyqtgraph available system-wide, use one of the methods listed below:
+
+* **Debian, Ubuntu, and similar Linux:** Download the .deb file linked at the top of the pyqtgraph web page or install using apt by putting "deb http://luke.campagnola.me/debian dev/" in your /etc/apt/sources.list file and install the python-pyqtgraph package.
+* **Arch Linux:** Looks like someone has posted unofficial packages for Arch (thanks windel). (https://aur.archlinux.org/packages.php?ID=62577)
+* **Windows:** Download and run the .exe installer file linked at the top of the pyqtgraph web page.

+Introduction
+============
+
+
+
+What is pyqtgraph?
+------------------
+
+PyQtGraph is a graphics and user interface library for Python that provides
+functionality commonly required in engineering and science applications. Its
+primary goals are 1) to provide fast, interactive graphics for displaying data
+(plots, video, etc.) and 2) to provide tools to aid in rapid application
+development (for example, property trees such as used in Qt Designer).
+
+PyQtGraph makes heavy use of the Qt GUI platform (via PyQt or PySide) for its
+high-performance graphics and numpy for heavy number crunching. In particular,
+pyqtgraph uses Qt's GraphicsView framework which is a highly capable graphics
+system on its own; we bring optimized and simplified primitives to this
+framework to allow data visualization with minimal effort.
+
+It is known to run on Linux, Windows, and OSX
+
+
+What can it do?
+---------------
+
+Amongst the core features of pyqtgraph are:
+
+* Basic data visualization primitives: Images, line and scatter plots
+* Fast enough for realtime update of video/plot data
+* Interactive scaling/panning, averaging, FFTs, SVG/PNG export
+* Widgets for marking/selecting plot regions
+* Widgets for marking/selecting image region-of-interest and automatically
+ slicing multi-dimensional image data
+* Framework for building customized image region-of-interest widgets
+* Docking system that replaces/complements Qt's dock system to allow more
+ complex (and more predictable) docking arrangements
+* ParameterTree widget for rapid prototyping of dynamic interfaces (Similar to
+ the property trees in Qt Designer and many other applications)
+
+
+.. _examples:
+
+Examples
+--------
+
+PyQtGraph includes an extensive set of examples that can be accessed by
+running::
+
+ import pyqtgraph.examples
+ pyqtgraph.examples.run()
+
+Or by running ``python examples/`` from the source root.
+
+This will start a launcher with a list of available examples. Select an item
+from the list to view its source code and double-click an item to run the
+example.
+
+Note If you have installed pyqtgraph with ``python setup.py develop``
+then the examples are incorrectly exposed as a top-level module. In this case,
+use ``import examples; examples.run()``.
+
+
+How does it compare to...
+-------------------------
+
+* matplotlib: For plotting, pyqtgraph is not nearly as complete/mature as
+ matplotlib, but runs much faster. Matplotlib is more aimed toward making
+ publication-quality graphics, whereas pyqtgraph is intended for use in data
+ acquisition and analysis applications. Matplotlib is more intuitive for
+ matlab programmers; pyqtgraph is more intuitive for python/qt programmers.
+ Matplotlib (to my knowledge) does not include many of pyqtgraph's features
+ such as image interaction, volumetric rendering, parameter trees,
+ flowcharts, etc.
+
+* pyqwt5: About as fast as pyqwt5, but not quite as complete for plotting
+ functionality. Image handling in pyqtgraph is much more complete (again, no
+ ROI widgets in qwt). Also, pyqtgraph is written in pure python, so it is
+ more portable than pyqwt, which often lags behind pyqt in development (I
+ originally used pyqwt, but decided it was too much trouble to rely on it
+ as a dependency in my projects). Like matplotlib, pyqwt (to my knowledge)
+ does not include many of pyqtgraph's features such as image interaction,
+ volumetric rendering, parameter trees, flowcharts, etc.
+
+(My experience with these libraries is somewhat outdated; please correct me if
+I am wrong here)

+Mouse Interaction
+=================
+
+Most applications that use pyqtgraph's data visualization will generate widgets that can be interactively scaled, panned, and otherwise configured using the mouse. This section describes mouse interaction with these widgets.
+
+
+2D Graphics
+-----------
+
+In pyqtgraph, most 2D visualizations follow the following mouse interaction:
+
+* Left button: Interacts with items in the scene (select/move objects, etc). If there are no movable objects under the mouse cursor, then dragging with the left button will pan the scene instead.
+* Right button drag: Scales the scene. Dragging left/right scales horizontally; dragging up/down scales vertically (although some scenes will have their x/y scales locked together). If there are x/y axes fisible in the scene, then right-dragging over the axis will _only_ affect that axis.
+* Right button click: Clicking the right button in most cases will show a context menu with a variety of options depending on the object(s) under the mouse cursor.
+* Middle button (or wheel) drag: Dragging the mouse with the wheel pressed down will always pan the scene (this is useful in instances where panning with the left button is prevented by other objects in the scene).
+* Wheel spin: Zooms the scene in and out.
+
+For machines where dragging with the right or middle buttons is difficult (usually Mac), another mouse interaction mode exists. In this mode, dragging with the left mouse button draws a box over a region of the scene. After the button is released, the scene is scaled and panned to fit the box. This mode can be accessed in the context menu or by calling::
+
+ pyqtgraph.setConfigOption('leftButtonPan', False)
+
+
+Context Menu
+------------
+
+Right-clicking on most scenes will show a context menu with various options for changing the behavior of the scene. Some of the options available in this menu are:
+
+* Enable/disable automatic scaling when the data range changes
+* Link the axes of multiple views together
+* Enable disable mouse interaction per axis
+* Explicitly set the visible range values
+
+The exact set of items available in the menu depends on the contents of the scene and the object clicked on.
+
+
+3D Graphics
+-----------
+
+3D visualizations use the following mouse interaction:
+
+* Left button drag: Rotates the scene around a central point
+* Middle button drag: Pan the scene by moving the central "look-at" point within the x-y plane
+* Middle button drag + CTRL: Pan the scene by moving the central "look-at" point along the z axis
+* Wheel spin: zoom in/out
+* Wheel + CTRL: change field-of-view angle
+
+And keyboard controls:
+
+* Arrow keys rotate around central point, just like dragging the left mouse button

+
+Parameter Trees
+===============
+
+Parameter trees are a system for handling hierarchies of parameters while automatically generating one or more GUIs to display and interact with the parameters.
+This feature is commonly seen, for example, in user interface design applications which display a list of editable properties for each widget.
+Parameters generally have a name, a data type (int, float, string, color, etc), and a value matching the data type. Parameters may be grouped and nested
+to form hierarchies and may be subclassed to provide custom behavior and display widgets.
+
+PyQtGraph's parameter tree system works similarly to the model-view architecture used by some components of Qt: Parameters are purely data-handling classes
+that exist independent of any graphical interface. A ParameterTree is a widget that automatically generates a graphical interface which represents
+the state of a haierarchy of Parameter objects and allows the user to edit the values within that hierarchy. This separation of data (model) and graphical
+interface (view) allows the same data to be represented multiple times and in a variety of different ways.
+

+Plotting in pyqtgraph
+=====================
+
+There are a few basic ways to plot data in pyqtgraph:
+
+=================================================================== ==================================================
+:func:`pyqtgraph.plot` Create a new plot window showing your data
+:func:`PlotWidget.plot() <pyqtgraph.PlotWidget.plot>` Add a new set of data to an existing plot widget
+:func:`PlotItem.plot() <pyqtgraph.PlotItem.plot>` Add a new set of data to an existing plot widget
+:func:`GraphicsLayout.addPlot() <pyqtgraph.GraphicsLayout.addPlot>` Add a new plot to a grid of plots
+=================================================================== ==================================================
+
+All of these will accept the same basic arguments which control how the plot data is interpreted and displayed:
+
+* x - Optional X data; if not specified, then a range of integers will be generated automatically.
+* y - Y data.
+* pen - The pen to use when drawing plot lines, or None to disable lines.
+* symbol - A string describing the shape of symbols to use for each point. Optionally, this may also be a sequence of strings with a different symbol for each point.
+* symbolPen - The pen (or sequence of pens) to use when drawing the symbol outline.
+* symbolBrush - The brush (or sequence of brushes) to use when filling the symbol.
+* fillLevel - Fills the area under the plot curve to this Y-value.
+* brush - The brush to use when filling under the curve.
+
+See the 'plotting' :ref:`example <examples>` for a demonstration of these arguments.
+
+All of the above functions also return handles to the objects that are created, allowing the plots and data to be further modified.
+
+Organization of Plotting Classes
+--------------------------------
+
+There are several classes invloved in displaying plot data. Most of these classes are instantiated automatically, but it is useful to understand how they are organized and relate to each other. PyQtGraph is based heavily on Qt's GraphicsView framework--if you are not already familiar with this, it's worth reading about (but not essential). Most importantly: 1) Qt GUIs are composed of QWidgets, 2) A special widget called QGraphicsView is used for displaying complex graphics, and 3) QGraphicsItems define the objects that are displayed within a QGraphicsView.
+
+* Data Classes (all subclasses of QGraphicsItem)
+ * :class:`PlotCurveItem <pyqtgraph.PlotCurveItem>` - Displays a plot line given x,y data
+ * :class:`ScatterPlotItem <pyqtgraph.ScatterPlotItem>` - Displays points given x,y data
+ * :class:`PlotDataItem <pyqtgraph.PlotDataItem>` - Combines PlotCurveItem and ScatterPlotItem. The plotting functions discussed above create objects of this type.
+* Container Classes (subclasses of QGraphicsItem; contain other QGraphicsItem objects and must be viewed from within a GraphicsView)
+ * :class:`PlotItem <pyqtgraph.PlotItem>` - Contains a ViewBox for displaying data as well as AxisItems and labels for displaying the axes and title. This is a QGraphicsItem subclass and thus may only be used from within a GraphicsView
+ * :class:`GraphicsLayout <pyqtgraph.GraphicsLayout>` - QGraphicsItem subclass which displays a grid of items. This is used to display multiple PlotItems together.
+ * :class:`ViewBox <pyqtgraph.ViewBox>` - A QGraphicsItem subclass for displaying data. The user may scale/pan the contents of a ViewBox using the mouse. Typically all PlotData/PlotCurve/ScatterPlotItems are displayed from within a ViewBox.
+ * :class:`AxisItem <pyqtgraph.AxisItem>` - Displays axis values, ticks, and labels. Most commonly used with PlotItem.
+* Container Classes (subclasses of QWidget; may be embedded in PyQt GUIs)
+ * :class:`PlotWidget <pyqtgraph.PlotWidget>` - A subclass of GraphicsView with a single PlotItem displayed. Most of the methods provided by PlotItem are also available through PlotWidget.
+ * :class:`GraphicsLayoutWidget <pyqtgraph.GraphicsLayoutWidget>` - QWidget subclass displaying a single GraphicsLayoutItem. Most of the methods provided by GraphicsLayoutItem are also available through GraphicsLayoutWidget.

+Rapid GUI prototyping
+=====================
+
+[Just an overview; documentation is not complete yet]
+
+PyQtGraph offers several powerful features which are commonly used in engineering and scientific applications.
+
+Parameter Trees
+---------------
+
+The parameter tree system provides a widget displaying a tree of modifiable values similar to those used in most GUI editor applications. This allows a large number of variables to be controlled by the user with relatively little programming effort. The system also provides separation between the data being controlled and the user interface controlling it (model/view architecture). Parameters may be grouped/nested to any depth and custom parameter types can be built by subclassing from Parameter and ParameterItem.
+
+See the `parametertree documentation <parametertree>`_ for more information.
+
+
+Visual Programming Flowcharts
+-----------------------------
+
+PyQtGraph's flowcharts provide a visual programming environment similar in concept to LabView--functional modules are added to a flowchart and connected by wires to define a more complex and arbitrarily configurable algorithm. A small number of predefined modules (called Nodes) are included with pyqtgraph, but most flowchart developers will want to define their own library of Nodes. At their core, the Nodes are little more than 1) a Python function 2) a list of input/output terminals, and 3) an optional widget providing a control panel for the Node. Nodes may transmit/receive any type of Python object via their terminals.
+
+See the `flowchart documentation <flowchart>`_ and the flowchart examples for more information.
+
+
+Graphical Canvas
+----------------
+
+The Canvas is a system designed to allow the user to add/remove items to a 2D canvas similar to most vector graphics applications. Items can be translated/scaled/rotated and each item may define its own custom control interface.
+
+
+Dockable Widgets
+----------------
+
+The dockarea system allows the design of user interfaces which can be rearranged by the user at runtime. Docks can be moved, resized, stacked, and torn out of the main window. This is similar in principle to the docking system built into Qt, but offers a more deterministic dock placement API (in Qt it is very difficult to programatically generate complex dock arrangements). Additionally, Qt's docks are designed to be used as small panels around the outer edge of a window. PyQtGraph's docks were created with the notion that the entire window (or any portion of it) would consist of dockable components.

+Qt Crash Course
+===============
+
+PyQtGraph makes extensive use of Qt for generating nearly all of its visual output and interfaces. Qt's documentation is very well written and we encourage all pyqtgraph developers to familiarize themselves with it. The purpose of this section is to provide an introduction to programming with Qt (using either PyQt or PySide) for the pyqtgraph developer.
+
+QWidgets and Layouts
+--------------------
+
+A Qt GUI is almost always composed of a few basic components:
+
+* A window. This is often provided by QMainWindow, but note that all QWidgets can be displayed in their window by simply calling widget.show() if the widget does not have a parent.
+* Multiple QWidget instances such as QPushButton, QLabel, QComboBox, etc.
+* QLayout instances (optional, but strongly encouraged) which automatically manage the positioning of widgets to allow the GUI to resize in a usable way.
+
+PyQtGraph fits into this scheme by providing its own QWidget subclasses to be inserted into your GUI.
+
+
+Example::
+
+ from PyQt4 import QtGui # (the example applies equally well to PySide)
+ import pyqtgraph as pg
+
+ ## Always start by initializing Qt (only once per application)
+ app = QtGui.QApplication([])
+
+ ## Define a top-level widget to hold everything
+ w = QtGui.QWidget()
+
+ ## Create some widgets to be placed inside
+ btn = QtGui.QPushButton('press me')
+ text = QtGui.QLineEdit('enter text')
+ listw = QtGui.QListWidget()
+ plot = pg.PlotWidget()
+
+ ## Create a grid layout to manage the widgets size and position
+ layout = QtGui.QGridLayout()
+ w.setLayout(layout)
+
+ ## Add widgets to the layout in their proper positions
+ layout.addWidget(btn, 0, 0) # button goes in upper-left
+ layout.addWidget(text, 1, 0) # text edit goes in middle-left
+ layout.addWidget(listw, 2, 0) # list widget goes in bottom-left
+ layout.addWidget(plot, 0, 1, 3, 1) # plot goes on right side, spanning 3 rows
+
+ ## Display the widget as a new window
+ w.show()
+
+ ## Start the Qt event loop
+ app.exec_()
+
+More complex interfaces may be designed graphically using Qt Designer, which allows you to simply drag widgets into your window to define its appearance.
+
+
+Naming Conventions
+------------------
+
+Virtually every class in pyqtgraph is an extension of base classes provided by Qt. When reading the documentation, remember that all of Qt's classes start with the letter 'Q', whereas pyqtgraph's classes do not. When reading through the methods for any class, it is often helpful to see which Qt base classes are used and look through the Qt documentation as well.
+
+Most of Qt's classes define signals which can be difficult to tell apart from regular methods. Almost all signals explicity defined by pyqtgraph are named beginning with 'sig' to indicate that these signals are not defined at the Qt level.
+
+In most cases, classes which end in 'Widget' are subclassed from QWidget and can therefore be used as a GUI element in a Qt window. Classes which end in 'Item' are subclasses of QGraphicsItem and can only be displayed within a QGraphicsView instance (such as GraphicsLayoutWidget or PlotWidget).
+
+
+Signals, Slots, and Events
+--------------------------
+
+[ to be continued.. please post a request on the pyqtgraph forum if you'd like to read more ]
+
+Qt detects and reacts to user interaction by executing its *event loop*.
+
+ - what happens in the event loop?
+ - when do I need to use QApplication.exec_() ?
+ - what control do I have over event loop execution? (QApplication.processEvents)

+Interactive Data Selection Controls
+===================================
+
+PyQtGraph includes graphics items which allow the user to select and mark regions of data.
+
+Linear Selection and Marking
+----------------------------
+
+Two classes allow marking and selecting 1-dimensional data: :class:`LinearRegionItem <pyqtgraph.LinearRegionItem>` and :class:`InfiniteLine <pyqtgraph.InfiniteLine>`. The first class, :class:`LinearRegionItem <pyqtgraph.LinearRegionItem>`, may be added to any ViewBox or PlotItem to mark either a horizontal or vertical region. The region can be dragged and its bounding edges can be moved independently. The second class, :class:`InfiniteLine <pyqtgraph.InfiniteLine>`, is usually used to mark a specific position along the x or y axis. These may be dragged by the user.
+
+
+2D Selection and Marking
+------------------------
+
+To select a 2D region from an image, pyqtgraph uses the :class:`ROI <pyqtgraph.ROI>` class or any of its subclasses. By default, :class:`ROI <pyqtgraph.ROI>` simply displays a rectangle which can be moved by the user to mark a specific region (most often this will be a region of an image, but this is not required). To allow the ROI to be resized or rotated, there are several methods for adding handles (:func:`addScaleHandle <pyqtgraph.ROI.addScaleHandle>`, :func:`addRotateHandle <pyqtgraph.ROI.addRotateHandle>`, etc.) which can be dragged by the user. These handles may be placed at any location relative to the ROI and may scale/rotate the ROI around any arbitrary center point. There are several ROI subclasses with a variety of shapes and modes of interaction.
+
+To automatically extract a region of image data using an ROI and an ImageItem, use :func:`ROI.getArrayRegion <pyqtgraph.ROI.getArrayRegion>`. ROI classes use the :func:`affineSlice <pyqtgraph.affineSlice>` function to perform this extraction.
+
+ROI can also be used as a control for moving/rotating/scaling items in a scene similar to most vetctor graphics editing applications.
+
+See the ROITypes example for more information.

+Line, Fill, and Color
+=====================
+
+Qt relies on its QColor, QPen and QBrush classes for specifying line and fill styles for all of its drawing.
+Internally, pyqtgraph uses the same system but also allows many shorthand methods of specifying
+the same style options.
+
+Many functions and methods in pyqtgraph accept arguments specifying the line style (pen), fill style (brush), or color.
+For most of these function arguments, the following values may be used:
+
+* single-character string representing color (b, g, r, c, m, y, k, w)
+* (r, g, b) or (r, g, b, a) tuple
+* single greyscale value (0.0 - 1.0)
+* (index, maximum) tuple for automatically iterating through colors (see :func:`intColor <pyqtgraph.intColor>`)
+* QColor
+* QPen / QBrush where appropriate
+
+Notably, more complex pens and brushes can be easily built using the
+:func:`mkPen() <pyqtgraph.mkPen>` / :func:`mkBrush() <pyqtgraph.mkBrush>` functions or with Qt's QPen and QBrush classes::
+
+ mkPen('y', width=3, style=QtCore.Qt.DashLine) ## Make a dashed yellow line 2px wide
+ mkPen(0.5) ## solid grey line 1px wide
+ mkPen(color=(200, 200, 255), style=QtCore.Qt.DotLine) ## Dotted pale-blue line
+
+See the Qt documentation for 'QPen' and 'PenStyle' for more line-style options and 'QBrush' for more fill options.
+Colors can also be built using :func:`mkColor() <pyqtgraph.mkColor>`,
+:func:`intColor() <pyqtgraph.intColor>`, :func:`hsvColor() <pyqtgraph.hsvColor>`, or Qt's QColor class.
+
+
+Default Background and Foreground Colors
+----------------------------------------
+
+By default, pyqtgraph uses a black background for its plots and grey for axes, text, and plot lines.
+These defaults can be changed using pyqtgraph.setConfigOption()::
+
+ import pyqtgraph as pg
+
+ ## Switch to using white background and black foreground
+ pg.setConfigOption('background', 'w')
+ pg.setConfigOption('foreground', 'k')
+
+ ## The following plot has inverted colors
+ pg.plot([1,4,2,3,5])
+
+(Note that this must be set *before* creating any widgets)

+This example demonstrates the use of RemoteGraphicsView to improve performance in
+applications with heavy load. It works by starting a second process to handle
+all graphics rendering, thus freeing up the main process to do its work.
+
+In this example, the update() function is very expensive and is called frequently.
+After update() generates a new set of data, it can either plot directly to a local
+plot (bottom) or remotely via a RemoteGraphicsView (top), allowing speed comparison
+between the two cases. IF you have a multi-core CPU, it should be obvious that the
+remote case is much faster.

+Demonstration of ScatterPlotWidget for exploring structure in tabular data.
+
+The widget consists of four components:
+
+1) A list of column names from which the user may select 1 or 2 columns
+ to plot. If one column is selected, the data for that column will be
+ plotted in a histogram-like manner by using pg.pseudoScatter().
+ If two columns are selected, then the
+ scatter plot will be generated with x determined by the first column
+ that was selected and y by the second.
+2) A DataFilter that allows the user to select a subset of the data by
+ specifying multiple selection criteria.
+3) A ColorMap that allows the user to determine how points are colored by
+ specifying multiple criteria.
+4) A PlotWidget for displaying the data.

+"""
+This example demonstrates the use of pyqtgraph's dock widget system.
+
+The dockarea system allows the design of user interfaces which can be rearranged by
+the user at runtime. Docks can be moved, resized, stacked, and torn out of the main
+window. This is similar in principle to the docking system built into Qt, but
+offers a more deterministic dock placement API (in Qt it is very difficult to
+programatically generate complex dock arrangements). Additionally, Qt's docks are
+designed to be used as small panels around the outer edge of a window. Pyqtgraph's
+docks were created with the notion that the entire window (or any portion of it)
+would consist of dockable components.

+In this example we create a subclass of PlotCurveItem for displaying a very large
+data set from an HDF5 file that does not fit in memory.
+
+The basic approach is to override PlotCurveItem.viewRangeChanged such that it
+reads only the portion of the HDF5 data that is necessary to display the visible
+portion of the data. This is further downsampled to reduce the number of samples
+being displayed.
+
+A more clever implementation of this class would employ some kind of caching
+to avoid re-reading the entire visible waveform at every update.

+ Extension of QGraphicsScene that implements a complete, parallel mouse event system.
+ (It would have been preferred to just alter the way QGraphicsScene creates and delivers
+ events, but this turned out to be impossible because the constructor for QGraphicsMouseEvent
+ is private)
+
+ * Generates MouseClicked events in addition to the usual press/move/release events.
+ (This works around a problem where it is impossible to have one item respond to a
+ drag if another is watching for a click.)
+ * Adjustable radius around click that will catch objects so you don't have to click *exactly* over small/thin objects
+ * Global context menu--if an item implements a context menu, then its parent(s) may also add items to the menu.
+ * Allows items to decide _before_ a mouse click which item will be the recipient of mouse events.
+ This lets us indicate unambiguously to the user which item they are about to click/drag on
+ * Eats mouseMove events that occur too soon after a mouse press.
+ * Reimplements items() and itemAt() to circumvent PyQt bug
+
+ Mouse interaction is as follows:
+
+ 1) Every time the mouse moves, the scene delivers both the standard hoverEnter/Move/LeaveEvents
+ as well as custom HoverEvents.
+ 2) Items are sent HoverEvents in Z-order and each item may optionally call event.acceptClicks(button),
+ acceptDrags(button) or both. If this method call returns True, this informs the item that _if_
+ the user clicks/drags the specified mouse button, the item is guaranteed to be the
+ recipient of click/drag events (the item may wish to change its appearance to indicate this).
+ If the call to acceptClicks/Drags returns False, then the item is guaranteed to *not* receive
+ the requested event (because another item has already accepted it).
+ 3) If the mouse is clicked, a mousePressEvent is generated as usual. If any items accept this press event, then
+ No click/drag events will be generated and mouse interaction proceeds as defined by Qt. This allows
+ items to function properly if they are expecting the usual press/move/release sequence of events.
+ (It is recommended that items do NOT accept press events, and instead use click/drag events)
+ Note: The default implementation of QGraphicsItem.mousePressEvent will *accept* the event if the
+ item is has its Selectable or Movable flags enabled. You may need to override this behavior.
+ 4) If no item accepts the mousePressEvent, then the scene will begin delivering mouseDrag and/or mouseClick events.
+ If the mouse is moved a sufficient distance (or moved slowly enough) before the button is released,
+ then a mouseDragEvent is generated.
+ If no drag events are generated before the button is released, then a mouseClickEvent is generated.
+ 5) Click/drag events are delivered to the item that called acceptClicks/acceptDrags on the HoverEvent
+ in step 1. If no such items exist, then the scene attempts to deliver the events to items near the event.
+ ClickEvents may be delivered in this way even if no
+ item originally claimed it could accept the click. DragEvents may only be delivered this way if it is the initial
+ move in a drag.

Some nodes implement fairly complex control widgets, but most nodes follow a simple form-like pattern: a list of parameter names and a single value (represented as spin box, check box, etc..) for each parameter.

+ Take a slice of any orientation through an array. This is useful for extracting sections of multi-dimensional arrays such as MRI images for viewing as 1D or 2D data.
+
+ The slicing axes are aribtrary; they do not need to be orthogonal to the original data or even to each other. It is possible to use this function to extract arbitrary linear, rectangular, or parallelepiped shapes from within larger datasets. The original data is interpolated onto a new array of coordinates using scipy.ndimage.map_coordinates if it is available (see the scipy documentation for more information about this). If scipy is not available, then a slower implementation of map_coordinates is used.
+
+ For a graphical interface to this function, see :func:`ROI.getArrayRegion <pyqtgraph.ROI.getArrayRegion>`

+ ============== ====================================================================================================
+ **Arguments:**
+ *data* (ndarray) the original dataset
+ *shape* the shape of the slice to take (Note the return value may have more dimensions than len(shape))
+ *origin* the location in the original dataset that will become the origin of the sliced data.
+ *vectors* list of unit vectors which point in the direction of the slice axes. Each vector must have the same
+ length as *axes*. If the vectors are not unit length, the result will be scaled relative to the
+ original data. If the vectors are not orthogonal, the result will be sheared relative to the
+ original data.
+ *axes* The axes in the original dataset which correspond to the slice *vectors*
+ *order* The order of spline interpolation. Default is 1 (linear). See scipy.ndimage.map_coordinates
+ for more information.
+ *returnCoords* If True, return a tuple (result, coords) where coords is the array of coordinates used to select

+
+ The GraphicsView system places a lot of emphasis on the notion that the graphics within the scene should be device independent--you should be able to take the same graphics and display them on screens of different resolutions, printers, export to SVG, etc. This is nice in principle, but causes me a lot of headache in practice. It means that I have to circumvent all the device-independent expectations any time I want to operate in pixel coordinates rather than arbitrary scene coordinates. A lot of the code in GraphicsItem is devoted to this task--keeping track of view widgets and device transforms, computing the size and shape of a pixel in local item coordinates, etc. Note that in item coordinates, a pixel does not have to be square or even rectangular, so just asking how to increase a bounding rect by 2px can be a rather complex task.

+ By default, this argument is true unless the levels argument is
+ given.
+ lut (numpy array) The color lookup table to use when displaying the image.
+ See :func:`setLookupTable <pyqtgraph.ImageItem.setLookupTable>`.
+ levels (min, max) The minimum and maximum values to use when rescaling the image
+ data. By default, this will be set to the minimum and maximum values
+ in the image. If the image array has dtype uint8, no rescaling is necessary.
+ opacity (float 0.0-1.0)
+ compositionMode See :func:`setCompositionMode <pyqtgraph.ImageItem.setCompositionMode>`
+ border Sets the pen used when drawing the image border. Default is None.
+ autoDownsample (bool) If True, the image is automatically downsampled to match the
+ screen resolution. This improves performance for large images and
+ reduces aliasing.
+ ================= =========================================================================

+
+ **Notes:**
+

+
+This class is one of the workhorses of pyqtgraph. It implements a graphics item with
+plots, labels, and scales which can be viewed inside a QGraphicsScene. If you want
+a widget that can be added to your GUI, see PlotWidget instead.
+
+This class is very heavily featured:
+ - Automatically creates and manages PlotCurveItems
+ - Fast display and update of plots
+ - Manages zoom/pan ViewBox, scale, and label elements
+ - Automatic scaling when data changes
+ - Control panel with a huge feature set including averaging, decimation,
+ display, power spectrum, svg/png export, plot linking, and more.

+ Generic region-of-interest widget.
+
+ Can be used for implementing many types of selection box with
+ rotate/translate/scale handles.
+ ROIs can be customized to have a variety of shapes (by subclassing or using
+ any of the built-in subclasses) and any combination of draggable handles
+ that allow the user to manipulate the ROI.
+
+
+
+ ================ ===========================================================
+ **Arguments**
+ pos (length-2 sequence) Indicates the position of the ROI's
+ origin. For most ROIs, this is the lower-left corner of
+ its bounding rectangle.
+ size (length-2 sequence) Indicates the width and height of the
+ ROI.
+ angle (float) The rotation of the ROI in degrees. Default is 0.
+ invertible (bool) If True, the user may resize the ROI to have
+ negative width or height (assuming the ROI has scale
+ handles). Default is False.
+ maxBounds (QRect, QRectF, or None) Specifies boundaries that the ROI
+ cannot be dragged outside of by the user. Default is None.
+ snapSize (float) The spacing of snap positions used when *scaleSnap*
+ or *translateSnap* are enabled. Default is 1.0.
+ scaleSnap (bool) If True, the width and height of the ROI are forced
+ to be integer multiples of *snapSize* when being resized
+ by the user. Default is False.
+ translateSnap (bool) If True, the x and y positions of the ROI are forced
+ to be integer multiples of *snapSize* when being resized
+ by the user. Default is False.
+ rotateSnap (bool) If True, the ROI angle is forced to a multiple of
+ 15 degrees when rotated by the user. Default is False.
+ parent (QGraphicsItem) The graphics item parent of this ROI. It
+ is generally not necessary to specify the parent.
+ pen (QPen or argument to pg.mkPen) The pen to use when drawing
+ the shape of the ROI.
+ movable (bool) If True, the ROI can be moved by dragging anywhere
+ inside the ROI. Default is True.
+ removable (bool) If True, the ROI will be given a context menu with
+ an option to remove the ROI. The ROI emits
+ sigRemoveRequested when this menu action is selected.
+ Default is False.
+ ================ ===========================================================
+
+
+
+ ======================= ====================================================
+ **Signals**
+ sigRegionChangeFinished Emitted when the user stops dragging the ROI (or
+ one of its handles) or if the ROI is changed
+ programatically.
+ sigRegionChangeStarted Emitted when the user starts dragging the ROI (or
+ one of its handles).
+ sigRegionChanged Emitted any time the position of the ROI changes,
+ including while it is being dragged by the user.
+ sigHoverEvent Emitted when the mouse hovers over the ROI.
+ sigClicked Emitted when the user clicks on the ROI.
+ Note that clicking is disabled by default to prevent
+ stealing clicks from objects behind the ROI. To
+ enable clicking, call
+ roi.setAcceptedMouseButtons(QtCore.Qt.LeftButton).
+ See QtGui.QGraphicsItem documentation for more
+ details.

+ ROI's context menu (if available).

+ **Keyword Arguments:**
+ *spots* Optional list of dicts. Each dict specifies parameters for a single spot:
+ {'pos': (x,y), 'size', 'pen', 'brush', 'symbol'}. This is just an alternate method
+ of passing in data for the corresponding arguments.
+ *x*,*y* 1D arrays of x,y values.
+ *pos* 2D structure of x,y pairs (such as Nx2 array or list of tuples)
+ *pxMode* If True, spots are always the same size regardless of scaling, and size is given in px.
+ Otherwise, size is in scene coordinates and the spots scale with the view.
+ Default is True
+ *symbol* can be one (or a list) of:
+ * 'o' circle (default)
+ * 's' square
+ * 't' triangle
+ * 'd' diamond
+ * '+' plus
+ * any QPainterPath to specify custom symbol shapes. To properly obey the position and size,
+ custom symbols should be centered at (0,0) and width and height of 1.0. Note that it is also
+ possible to 'install' custom shapes by setting ScatterPlotItem.Symbols[key] = shape.
+ *pen* The pen (or list of pens) to use for drawing spot outlines.
+ *brush* The brush (or list of brushes) to use for filling spots.
+ *size* The size (or list of sizes) of spots. If *pxMode* is True, this value is in pixels. Otherwise,
+ it is in the item's local coordinate system.
+ *data* a list of python objects used to uniquely identify each spot.
+ *identical* *Deprecated*. This functionality is handled automatically now.
+ *antialias* Whether to draw symbols with antialiasing. Note that if pxMode is True, symbols are
+ always rendered with antialiasing (since the rendered symbols can be cached, this
+ incurs very little performance cost)
+ *name* The name of this item. Names are used for automatically
+ generating LegendItem entries and by some exporters.

+ *anchor* A QPointF or (x,y) sequence indicating what region of the text box will

+ of the text box to be at the position specified by setPos(), while a value of (1,1)

+ *border* A pen to use when drawing the border
+ *fill* A brush to use when filling within the border
+ *angle* Angle in degrees to rotate text. Default is 0; text will be displayed upright.
+ *rotateAxis* If None, then a text angle of 0 always points along the +x axis of the scene.

+
+ The info argument sets the metadata for the entire array. It is composed of a list
+ of axis descriptions where each axis may have a name, title, units, and a list of column
+ descriptions. An additional dict at the end of the axis list may specify parameters
+ that apply to values in the entire array.
+
+ For example:
+ A 2D array of altitude values for a topographical map might look like
+ info=[
+ {'name': 'lat', 'title': 'Lattitude'},
+ {'name': 'lon', 'title': 'Longitude'},
+ {'title': 'Altitude', 'units': 'm'}

+ position represented by the array index. All of the following return the
+ value at lat=10, lon=5:
+ array[10, 5]
+ array['lon':5, 'lat':10]
+ array['lat':10][5]
+ Now suppose we want to combine this data with another array of equal dimensions that
+ represents the average rainfall for each location. We could easily store these as two
+ separate arrays or combine them into a 3D array with this description:
+ info=[
+ {'name': 'vals', 'cols': [
+ {'name': 'altitude', 'units': 'm'},
+ {'name': 'rainfall', 'units': 'cm/year'}
+ ]},
+ {'name': 'lat', 'title': 'Lattitude'},
+ {'name': 'lon', 'title': 'Longitude'}
+ ]
+ We can now access the altitude values with array[0] or array['altitude'], and the
+ rainfall values with array[1] or array['rainfall']. All of the following return
+ the rainfall value at lat=10, lon=5:
+ array[1, 10, 5]
+ array['lon':5, 'lat':10, 'val': 'rainfall']
+ array['rainfall', 'lon':5, 'lat':10]
+ Notice that in the second example, there is no need for an extra (4th) axis description
+ since the actual values are described (name and units) in the column info for the first axis.

+ A Parameter is the basic unit of data in a parameter tree. Each parameter has

+ interpretation; instead they manage ParameterItem instances which take care of
+ display and user interaction.
+
+ Note: It is fairly uncommon to use the Parameter class directly; mostly you
+ will use subclasses which provide specialized type and data handling. The static

+
+class SystemSolver(object):
+ """
+ This abstract class is used to formalize and manage user interaction with a
+ complex system of equations (related to "constraint satisfaction problems").
+ It is often the case that devices must be controlled
+ through a large number of free variables, and interactions between these
+ variables make the system difficult to manage and conceptualize as a user
+ interface. This class does _not_ attempt to numerically solve the system
+ of equations. Rather, it provides a framework for subdividing the system
+ into manageable pieces and specifying closed-form solutions to these small
+ pieces.
+
+ For an example, see the simple Camera class below.
+
+ Theory of operation: Conceptualize the system as 1) a set of variables
+ whose values may be either user-specified or automatically generated, and
+ 2) a set of functions that define *how* each variable should be generated.
+ When a variable is accessed (as an instance attribute), the solver first
+ checks to see if it already has a value (either user-supplied, or cached
+ from a previous calculation). If it does not, then the solver calls a
+ method on itself (the method must be named `_variableName`) that will
+ either return the calculated value (which usually involves acccessing
+ other variables in the system), or raise RuntimeError if it is unable to
+ calculate the value (usually because the user has not provided sufficient
+ input to fully constrain the system).
+
+ Each method that calculates a variable value may include multiple
+ try/except blocks, so that if one method generates a RuntimeError, it may
+ fall back on others.
+ In this way, the system may be solved by recursively searching the tree of
+ possible relationships between variables. This allows the user flexibility
+ in deciding which variables are the most important to specify, while
+ avoiding the apparent combinatorial explosion of calculation pathways
+ that must be considered by the developer.
+
+ Solved values are cached for efficiency, and automatically cleared when
+ a state change invalidates the cache. The rules for this are simple: any
+ time a value is set, it invalidates the cache *unless* the previous value
+ was None (which indicates that no other variable has yet requested that
+ value). More complex cache management may be defined in subclasses.
+
+
+ Subclasses must define:
+
+ 1) The *defaultState* class attribute: This is a dict containing a
+ description of the variables in the system--their default values,
+ data types, and the ways they can be constrained. The format is::
+
+ { name: [value, type, constraint, allowed_constraints], ...}
+
+ * *value* is the default value. May be None if it has not been specified
+ yet.
+ * *type* may be float, int, bool, np.ndarray, ...
+ * *constraint* may be None, single value, or (min, max)
+ * None indicates that the value is not constrained--it may be
+ automatically generated if the value is requested.
+ * *allowed_constraints* is a string composed of (n)one, (f)ixed, and (r)ange.
+
+ Note: do not put mutable objects inside defaultState!
+
+ 2) For each variable that may be automatically determined, a method must
+ be defined with the name `_variableName`. This method may either return

+ Consider a simple SLR camera. The variables we will consider that
+ affect the camera's behavior while acquiring a photo are aperture, shutter speed,
+ ISO, and flash (of course there are many more, but let's keep the example simple).
+
+ In rare cases, the user wants to manually specify each of these variables and
+ no more work needs to be done to take the photo. More often, the user wants to
+ specify more interesting constraints like depth of field, overall exposure,
+ or maximum allowed ISO value.
+
+ If we add a simple light meter measurement into this system and an 'exposure'
+ variable that indicates the desired exposure (0 is "perfect", -1 is one stop
+ darker, etc), then the system of equations governing the camera behavior would
+ have the following variables:
+
+ aperture, shutter, iso, flash, exposure, light meter
+
+ The first four variables are the "outputs" of the system (they directly drive
+ the camera), the last is a constant (the camera itself cannot affect the
+ reading on the light meter), and 'exposure' specifies a desired relationship
+ between other variables in the system.
+
+ So the question is: how can I formalize a system like this as a user interface?
+ Typical cameras have a fairly limited approach: provide the user with a list
+ of modes, each of which defines a particular set of constraints. For example:
+
+ manual: user provides aperture, shutter, iso, and flash
+ aperture priority: user provides aperture and exposure, camera selects
+ iso, shutter, and flash automatically
+ shutter priority: user provides shutter and exposure, camera selects
+ iso, aperture, and flash
+ program: user specifies exposure, camera selects all other variables
+ automatically
+ action: camera selects all variables while attempting to maximize
+ shutter speed
+ portrait: camera selects all variables while attempting to minimize
+ aperture
+
+ A more general approach might allow the user to provide more explicit
+ constraints on each variable (for example: I want a shutter speed of 1/30 or
+ slower, an ISO no greater than 400, an exposure between -1 and 1, and the
+ smallest aperture possible given all other constraints) and have the camera
+ solve the system of equations, with a warning if no solution is found. This
+ is exactly what we will implement in this example class.

+Procedure for unit-testing with images:
+
+1. Run unit tests at least once; this initializes a git clone of
+ pyqtgraph/test-data in ~/.pyqtgraph.
+
+2. Run individual test scripts with the PYQTGRAPH_AUDIT environment variable set:
+
+ $ PYQTGRAPH_AUDIT=1 python pyqtgraph/graphicsItems/tests/test_PlotCurveItem.py
+
+ Any failing tests will
+ display the test results, standard image, and the differences between the
+ two. If the test result is bad, then press (f)ail. If the test result is
+ good, then press (p)ass and the new image will be saved to the test-data
+ directory.
+
+3. After adding or changing test images, create a new commit:
+
+ $ cd ~/.pyqtgraph/test-data
+ $ git add ...
+ $ git commit -a
+
+4. Look up the most recent tag name from the `testDataTag` global variable
+ below. Increment the tag name by 1 and create a new tag in the test-data
+ repository:
+
+ $ git tag test-data-NNN
+ $ git push --tags origin master
+
+ This tag is used to ensure that each pyqtgraph commit is linked to a specific
+ commit in the test-data repository. This makes it possible to push new
+ commits to the test-data repository without interfering with existing
+ tests, and also allows unit tests to continue working on older pyqtgraph
+ versions.
+
+"""

+
+# This is the name of a tag in the test-data repository that this version of
+# pyqtgraph should be tested against. When adding or changing test images,
+# create and push a new tag and update this variable. To test locally, begin
+# by creating the tag in your ~/.pyqtgraph/test-data repository.

+ **Arguments:**
+ parent Sets the parent widget for this SpinBox (optional). Default is None.
+ value (float/int) initial value. Default is 0.0.
+ bounds (min,max) Minimum and maximum values allowed in the SpinBox.
+ Either may be None to leave the value unbounded. By default, values are unbounded.
+ suffix (str) suffix (units) to display after the numerical value. By default, suffix is an empty str.
+ siPrefix (bool) If True, then an SI prefix is automatically prepended
+ to the units and the value is scaled accordingly. For example,
+ if value=0.003 and suffix='V', then the SpinBox will display
+ "300 mV" (but a call to SpinBox.value will still return 0.003). Default is False.
+ step (float) The size of a single step. This is used when clicking the up/
+ down arrows, when rolling the mouse wheel, or when pressing
+ keyboard arrows while the widget has keyboard focus. Note that
+ the interpretation of this value is different when specifying
+ the 'dec' argument. Default is 0.01.
+ dec (bool) If True, then the step value will be adjusted to match
+ the current size of the variable (for example, a value of 15
+ might step in increments of 1 whereas a value of 1500 would
+ step in increments of 100). In this case, the 'step' argument
+ is interpreted *relative* to the current value. The most common
+ 'step' values when dec=True are 0.1, 0.2, 0.5, and 1.0. Default is False.
+ minStep (float) When dec=True, this specifies the minimum allowable step size.
+ int (bool) if True, the value is forced to integer type. Default is False
+ decimals (int) Number of decimal values to display. Default is 2.

+PyQtGraph Release Procedure
+---------------------------
+
+1. Create a release-x.x.x branch
+
+2. Run pyqtgraph/tools/pg-release.py script (this has only been tested on linux)
+ - creates clone of master
+ - merges release branch into master
+ - updates version numbers in code
+ - creates pyqtgraph-x.x.x tag
+ - creates release commit
+ - builds documentation
+ - builds source package
+ - tests pip install
+ - builds windows .exe installers (note: it may be necessary to manually
+ copy wininst*.exe files from the python source packages)
+ - builds deb package (note: official debian packages are built elsewhere;
+ these locally-built deb packages may be phased out)
+
+3. test build files
+ - test setup.py, pip on OSX
+ - test setup.py, pip, 32/64 exe on windows
+ - test setup.py, pip, deb on linux (py2, py3)
+
+4. Run pg-release.py script again with --publish flag
+ - website upload
+ - github push + release
+ - pip upload
+
+5. publish
+ - update website
+ - mailing list announcement
+ - new conda recipe (http://conda.pydata.org/docs/build.html)
+ - contact various package maintainers
