+ """
+ 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.
+ 3) 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.
+ 4) 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.

-PlotItem.py - Graphics item implementing a scalable ViewBox with plotting powers.
-Copyright 2010 Luke Campagnola
-Distributed under MIT/X11 license. See license.txt for more infomation.
-
-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.

+Pyqtgraph's Helper Functions
+============================
+
+Simple Data Display Functions
+-----------------------------
+
+.. autofunction:: pyqtgraph.plot
+
+.. autofunction:: pyqtgraph.image
+
+
+
+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. I don't think it could reasonably be any simpler than that. The call to pg.plot returns a handle to the plot widget that is created, allowing more data to be added to the same window.
+
+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 widgets that can be embedded just like any other Qt widgets. Most importantly, see: PlotWidget, ImageView, GraphicsView, GraphicsLayoutWidget. Pyqtgraph's widgets can be included in Designer's ui files via the "Promote To..." functionality.

+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 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`.

+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()
+
+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.
+
+
+How does it compare to...
+-------------------------
+
+* matplotlib: For plotting and making publication-quality graphics, matplotlib is far more mature than pyqtgraph. However, matplotlib is also much slower and not suitable for applications requiring realtime update of plots/video or rapid interactivity. It also does not provide any of the GUI tools and image interaction/slicing functionality in pyqtgraph.
+
+* pyqwt5: pyqwt is generally more mature than pyqtgraph for plotting and is about as fast. The major differences are 1) pyqtgraph is written in pure python, so it is somewhat more portable than pyqwt, which often lags behind pyqt in development (and can be a pain to install on some platforms) and 2) like matplotlib, pyqwt does not provide any of the GUI tools and image interaction/slicing functionality in pyqtgraph.
+
+(My experience with these libraries is somewhat outdated; please correct me if I am wrong here)

+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:`GraphicsWindow.addPlot() <pyqtgraph.GraphicsWindow.plot>` 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)
+ * PlotCurveItem - Displays a plot line given x,y data
+ * ScatterPlotItem - Displays points given x,y data
+ * :class:`PlotDataItem <pyqtgraph.graphicsItems.PlotDataItem.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)
+ * 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
+ * GraphicsLayoutItem - QGraphicsItem subclass which displays a grid of items. This is used to display multiple PlotItems together.
+ * 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.
+ * AxisItem - Displays axis values, ticks, and labels. Most commonly used with PlotItem.
+* Container Classes (subclasses of QWidget; may be embedded in PyQt GUIs)
+ * PlotWidget - A subclass of GraphicsView with a single PlotItem displayed. Most of the methods provided by PlotItem are also available through PlotWidget.
+ * GraphicsLayoutWidget - QWidget subclass displaying a single GraphicsLayoutItem. Most of the methods provided by GraphicsLayoutItem are also available through GraphicsLayoutWidget.

+Examples
+--------
+
+See the 'plotting' and 'PlotWidget' :ref:`examples included with pyqtgraph <examples>` for more information.
+
+Show x,y data as scatter plot::
+
+ import pyqtgraph as pg
+ import numpy as np
+ x = np.random.normal(size=1000)
+ y = np.random.normal(size=1000)
+ pg.plot(x, y, pen=None, symbol='o') ## setting pen=None disables line drawing
+
+Create/show a plot widget, display three data curves::
+
+ import pyqtgraph as pg
+ import numpy as np
+ x = np.arange(1000)
+ y = np.random.normal(size=(3, 1000))
+ plotWidget = pg.plot(title="Three plot curves")
+ for i in range(3):
+ plotWidget.plot(x, y[i], pen=(i,3)) ## setting pen=(i,3) automaticaly creates three different-colored pens

+Line, Fill, and Color
+=====================
+
+Many functions and methods in pyqtgraph accept arguments specifying the line style (pen), fill style (brush), or color.
+
+For 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 functions.intColor)
+* QColor
+* QPen / QBrush where appropriate
+
+Notably, more complex pens and brushes can be easily built using the mkPen() / mkBrush() functions or with Qt's QPen and QBrush classes.
+
+Colors can also be built using mkColor(), intColor(), hsvColor(), or Qt's QColor class

+ * This script makes the Sphinx sidebar collapsible.
+ *
+ * .sphinxsidebar contains .sphinxsidebarwrapper. This script adds
+ * in .sphixsidebar, after .sphinxsidebarwrapper, the #sidebarbutton
+ * used to collapse and expand the sidebar.
+ *
+ * When the sidebar is collapsed the .sphinxsidebarwrapper is hidden
+ * and the width of the sidebar and the margin-left of the document
+ * are decreased. When the sidebar is expanded the opposite happens.
+ * This script saves a per-browser/per-session cookie used to
+ * remember the position of the sidebar among the pages.
+ * Once the browser is closed the cookie is deleted and the position
+ * reset to the default (expanded).

+<p>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 <a class="reference internal" href="#pyqtgraph.mkColor" title="pyqtgraph.mkColor"><tt class="xref py py-func docutils literal"><span class="pre">mkColor()</span></tt></a>, <a class="reference internal" href="#pyqtgraph.mkPen" title="pyqtgraph.mkPen"><tt class="xref py py-func docutils literal"><span class="pre">mkPen()</span></tt></a>, and <a class="reference internal" href="#pyqtgraph.mkBrush" title="pyqtgraph.mkBrush"><tt class="xref py py-func docutils literal"><span class="pre">mkBrush()</span></tt></a> 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 <em>pen</em> or <em>brush</em> arguments will make use of these functions for you. For example, the following three lines all have the same effect:</p>

+<dd><p>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.</p>
+<p>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.</p>
+<p>For a graphical interface to this function, see <tt class="xref py py-func docutils literal"><span class="pre">ROI.getArrayRegion()</span></tt></p>
+<p>Arguments:</p>
+<blockquote>
+<div class="line-block">

+<div class="line"><em>vectors</em>: list of unit vectors which point in the direction of the slice axes</div>

+<ul class="simple">
+<li>each vector must have the same length as <em>axes</em></li>
+<li>If the vectors are not unit length, the result will be scaled.</li>
+<li>If the vectors are not orthogonal, the result will be sheared.</li>
+</ul>

+<p>Example: start with a 4D fMRI data set, take a diagonal-planar slice out of the last 3 axes</p>
+<blockquote>
+<ul class="simple">
+<li>data = array with dims (time, x, y, z) = (100, 40, 40, 40)</li>
+<li>The plane to pull out is perpendicular to the vector (x,y,z) = (1,1,1)</li>
+<li>The origin of the slice will be at (x,y,z) = (40, 0, 0)</li>
+<li>We will slice a 20x20 plane from each timepoint, giving a final shape (100, 20, 20)</li>
+</ul>

+<h1>Pyqtgraph’s Graphics Items<a class="headerlink" href="#pyqtgraph-s-graphics-items" title="Permalink to this headline">¶</a></h1>
+<p>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.</p>

+<h1>How to use pyqtgraph<a class="headerlink" href="#how-to-use-pyqtgraph" title="Permalink to this headline">¶</a></h1>
+<p>There are a few suggested ways to use pyqtgraph:</p>
+<ul class="simple">
+<li>From the interactive shell (python -i, ipython, etc)</li>
+<li>Displaying pop-up windows from an application</li>
+<li>Embedding widgets in a PyQt application</li>
+</ul>
+<div class="section" id="command-line-use">
+<h2>Command-line use<a class="headerlink" href="#command-line-use" title="Permalink to this headline">¶</a></h2>
+<p>Pyqtgraph makes it very easy to visualize data from the command line. Observe:</p>
+<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">pyqtgraph</span> <span class="kn">as</span> <span class="nn">pg</span>

+</pre></div>
+</div>
+<p>The example above would open a window displaying a line plot of the data given. I don’t think it could reasonably be any simpler than that. The call to pg.plot returns a handle to the plot widget that is created, allowing more data to be added to the same window.</p>

+<p>We’re only scratching the surface here–these functions accept many different data formats and options for customizing the appearance of your data.</p>

+<h2>Displaying windows from within an application<a class="headerlink" href="#displaying-windows-from-within-an-application" title="Permalink to this headline">¶</a></h2>
+<p>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.</p>

+<p>For the serious application developer, all of the functionality in pyqtgraph is available via widgets that can be embedded just like any other Qt widgets. Most importantly, see: PlotWidget, ImageView, GraphicsView, GraphicsLayoutWidget. Pyqtgraph’s widgets can be included in Designer’s ui files via the “Promote To...” functionality.</p>

+<h1>Displaying images and video<a class="headerlink" href="#displaying-images-and-video" title="Permalink to this headline">¶</a></h1>
+<p>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).</p>
+<p>The easiest way to display 2D or 3D data is using the <a class="reference internal" href="functions.html#pyqtgraph.image" title="pyqtgraph.image"><tt class="xref py py-func docutils literal"><span class="pre">pyqtgraph.image()</span></tt></a> function:</p>
+<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">pyqtgraph</span> <span class="kn">as</span> <span class="nn">pg</span>
+<span class="n">pg</span><span class="o">.</span><span class="n">image</span><span class="p">(</span><span class="n">imageData</span><span class="p">)</span>
+</pre></div>
+</div>
+<p>This function will accept any floating-point or integer data types and displays a single <a class="reference internal" href="widgets/imageview.html#pyqtgraph.ImageView" title="pyqtgraph.ImageView"><tt class="xref py py-class docutils literal"><span class="pre">ImageView</span></tt></a> 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):</p>
+<ol class="arabic simple">
+<li>Scale and offset the data (by selecting the dark/light levels on the displayed histogram)</li>
+<li>Convert the data to color using a lookup table (determined by the colors shown in the gradient editor)</li>
+</ol>
+<p>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)</p>
+<p>There are a few other methods for displaying images as well:</p>
+<ul class="simple">
+<li>The <a class="reference internal" href="widgets/imageview.html#pyqtgraph.ImageView" title="pyqtgraph.ImageView"><tt class="xref py py-class docutils literal"><span class="pre">ImageView</span></tt></a> class can also be instantiated directly and embedded in Qt applications.</li>
+<li>Instances of <a class="reference internal" href="graphicsItems/imageitem.html#pyqtgraph.ImageItem" title="pyqtgraph.ImageItem"><tt class="xref py py-class docutils literal"><span class="pre">ImageItem</span></tt></a> can be used inside a GraphicsView.</li>
+<li>For higher performance, use <a class="reference internal" href="widgets/rawimagewidget.html#pyqtgraph.RawImageWidget" title="pyqtgraph.RawImageWidget"><tt class="xref py py-class docutils literal"><span class="pre">RawImageWidget</span></tt></a>.</li>
+</ul>
+<p>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.</p>
+<p>For more information, see the classes listed above and the ‘VideoSpeedTest’, ‘ImageItem’, ‘ImageView’, and ‘HistogramLUT’ <a class="reference internal" href="introduction.html#examples"><em>Examples</em></a>.</p>

+<h2>What is pyqtgraph?<a class="headerlink" href="#what-is-pyqtgraph" title="Permalink to this headline">¶</a></h2>
+<p>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).</p>
+<p>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.</p>
+<p>It is known to run on Linux, Windows, and OSX</p>
+</div>
+<div class="section" id="what-can-it-do">
+<h2>What can it do?<a class="headerlink" href="#what-can-it-do" title="Permalink to this headline">¶</a></h2>
+<p>Amongst the core features of pyqtgraph are:</p>
+<ul class="simple">
+<li>Basic data visualization primitives: Images, line and scatter plots</li>
+<li>Fast enough for realtime update of video/plot data</li>
+<li>Interactive scaling/panning, averaging, FFTs, SVG/PNG export</li>
+<li>Widgets for marking/selecting plot regions</li>
+<li>Widgets for marking/selecting image region-of-interest and automatically slicing multi-dimensional image data</li>
+<li>Framework for building customized image region-of-interest widgets</li>
+<li>Docking system that replaces/complements Qt’s dock system to allow more complex (and more predictable) docking arrangements</li>
+<li>ParameterTree widget for rapid prototyping of dynamic interfaces (Similar to the property trees in Qt Designer and many other applications)</li>
+</ul>
+</div>
+<div class="section" id="examples">
+<span id="id1"></span><h2>Examples<a class="headerlink" href="#examples" title="Permalink to this headline">¶</a></h2>
+<p>Pyqtgraph includes an extensive set of examples that can be accessed by running:</p>
+<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">pyqtgraph.examples</span>
+<span class="n">pyqtgraph</span><span class="o">.</span><span class="n">examples</span><span class="o">.</span><span class="n">run</span><span class="p">()</span>
+</pre></div>
+</div>
+<p>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.</p>
+</div>
+<div class="section" id="how-does-it-compare-to">
+<h2>How does it compare to...<a class="headerlink" href="#how-does-it-compare-to" title="Permalink to this headline">¶</a></h2>
+<ul class="simple">
+<li>matplotlib: For plotting and making publication-quality graphics, matplotlib is far more mature than pyqtgraph. However, matplotlib is also much slower and not suitable for applications requiring realtime update of plots/video or rapid interactivity. It also does not provide any of the GUI tools and image interaction/slicing functionality in pyqtgraph.</li>
+<li>pyqwt5: pyqwt is generally more mature than pyqtgraph for plotting and is about as fast. The major differences are 1) pyqtgraph is written in pure python, so it is somewhat more portable than pyqwt, which often lags behind pyqt in development (and can be a pain to install on some platforms) and 2) like matplotlib, pyqwt does not provide any of the GUI tools and image interaction/slicing functionality in pyqtgraph.</li>
+</ul>
+<p>(My experience with these libraries is somewhat outdated; please correct me if I am wrong here)</p>

+<h2>Organization of Plotting Classes<a class="headerlink" href="#organization-of-plotting-classes" title="Permalink to this headline">¶</a></h2>
+<p>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.</p>
+<ul>
+<li><dl class="first docutils">
+<dt>Data Classes (all subclasses of QGraphicsItem)</dt>
+<dd><ul class="first last simple">
+<li>PlotCurveItem - Displays a plot line given x,y data</li>
+<li>ScatterPlotItem - Displays points given x,y data</li>
+<li><tt class="xref py py-class docutils literal"><span class="pre">PlotDataItem</span></tt> - Combines PlotCurveItem and ScatterPlotItem. The plotting functions discussed above create objects of this type.</li>
+</ul>
+</dd>
+</dl>
+</li>
+<li><dl class="first docutils">
+<dt>Container Classes (subclasses of QGraphicsItem; contain other QGraphicsItem objects and must be viewed from within a GraphicsView)</dt>
+<dd><ul class="first last simple">
+<li>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</li>
+<li>GraphicsLayoutItem - QGraphicsItem subclass which displays a grid of items. This is used to display multiple PlotItems together.</li>
+<li>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.</li>
+<li>AxisItem - Displays axis values, ticks, and labels. Most commonly used with PlotItem.</li>
+</ul>

+<li><dl class="first docutils">
+<dt>Container Classes (subclasses of QWidget; may be embedded in PyQt GUIs)</dt>

+<li>PlotWidget - A subclass of GraphicsView with a single PlotItem displayed. Most of the methods provided by PlotItem are also available through PlotWidget.</li>

+<h1>Line, Fill, and Color<a class="headerlink" href="#line-fill-and-color" title="Permalink to this headline">¶</a></h1>
+<p>Many functions and methods in pyqtgraph accept arguments specifying the line style (pen), fill style (brush), or color.</p>
+<p>For these function arguments, the following values may be used:</p>
+<ul class="simple">
+<li>single-character string representing color (b, g, r, c, m, y, k, w)</li>
+<li>(r, g, b) or (r, g, b, a) tuple</li>
+<li>single greyscale value (0.0 - 1.0)</li>
+<li>(index, maximum) tuple for automatically iterating through colors (see functions.intColor)</li>
+<li>QColor</li>
+<li>QPen / QBrush where appropriate</li>
+</ul>
+<p>Notably, more complex pens and brushes can be easily built using the mkPen() / mkBrush() functions or with Qt’s QPen and QBrush classes.</p>
+<p>Colors can also be built using mkColor(), intColor(), hsvColor(), or Qt’s QColor class</p>

+Pyqtgraph's Helper Functions
+============================
+
+Simple Data Display Functions
+-----------------------------
+
+.. autofunction:: pyqtgraph.plot
+
+.. autofunction:: pyqtgraph.image
+
+
+
+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)))
+
+
+.. autofunction:: pyqtgraph.mkColor
+
+.. autofunction:: pyqtgraph.mkPen
+
+.. autofunction:: pyqtgraph.mkBrush
+
+.. autofunction:: pyqtgraph.hsvColor
+
+.. autofunction:: pyqtgraph.intColor
+
+.. autofunction:: pyqtgraph.colorTuple
+
+.. autofunction:: pyqtgraph.colorStr

+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. I don't think it could reasonably be any simpler than that. The call to pg.plot returns a handle to the plot widget that is created, allowing more data to be added to the same window.
+
+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 widgets that can be embedded just like any other Qt widgets. Most importantly, see: PlotWidget, ImageView, GraphicsView, GraphicsLayoutWidget. Pyqtgraph's widgets can be included in Designer's ui files via the "Promote To..." functionality.

+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 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`.

+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()
+
+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.
+
+
+How does it compare to...
+-------------------------
+
+* matplotlib: For plotting and making publication-quality graphics, matplotlib is far more mature than pyqtgraph. However, matplotlib is also much slower and not suitable for applications requiring realtime update of plots/video or rapid interactivity. It also does not provide any of the GUI tools and image interaction/slicing functionality in pyqtgraph.
+
+* pyqwt5: pyqwt is generally more mature than pyqtgraph for plotting and is about as fast. The major differences are 1) pyqtgraph is written in pure python, so it is somewhat more portable than pyqwt, which often lags behind pyqt in development (and can be a pain to install on some platforms) and 2) like matplotlib, pyqwt does not provide any of the GUI tools and image interaction/slicing functionality in pyqtgraph.
+
+(My experience with these libraries is somewhat outdated; please correct me if I am wrong here)

+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:`GraphicsWindow.addPlot() <pyqtgraph.GraphicsWindow.plot>` 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)
+ * PlotCurveItem - Displays a plot line given x,y data
+ * ScatterPlotItem - Displays points given x,y data
+ * :class:`PlotDataItem <pyqtgraph.graphicsItems.PlotDataItem.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)
+ * 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
+ * GraphicsLayoutItem - QGraphicsItem subclass which displays a grid of items. This is used to display multiple PlotItems together.
+ * 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.
+ * AxisItem - Displays axis values, ticks, and labels. Most commonly used with PlotItem.
+* Container Classes (subclasses of QWidget; may be embedded in PyQt GUIs)
+ * PlotWidget - A subclass of GraphicsView with a single PlotItem displayed. Most of the methods provided by PlotItem are also available through PlotWidget.
+ * GraphicsLayoutWidget - QWidget subclass displaying a single GraphicsLayoutItem. Most of the methods provided by GraphicsLayoutItem are also available through GraphicsLayoutWidget.

+
+Examples
+--------
+
+See the 'plotting' and 'PlotWidget' :ref:`examples included with pyqtgraph <examples>` for more information.
+
+Show x,y data as scatter plot::
+
+ import pyqtgraph as pg
+ import numpy as np
+ x = np.random.normal(size=1000)
+ y = np.random.normal(size=1000)
+ pg.plot(x, y, pen=None, symbol='o') ## setting pen=None disables line drawing
+
+Create/show a plot widget, display three data curves::
+
+ import pyqtgraph as pg
+ import numpy as np
+ x = np.arange(1000)
+ y = np.random.normal(size=(3, 1000))
+ plotWidget = pg.plot(title="Three plot curves")
+ for i in range(3):
+ plotWidget.plot(x, y[i], pen=(i,3)) ## setting pen=(i,3) automaticaly creates three different-colored pens

+Line, Fill, and Color
+=====================
+
+Many functions and methods in pyqtgraph accept arguments specifying the line style (pen), fill style (brush), or color.
+
+For 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 functions.intColor)
+* QColor
+* QPen / QBrush where appropriate
+
+Notably, more complex pens and brushes can be easily built using the mkPen() / mkBrush() functions or with Qt's QPen and QBrush classes.
+
+Colors can also be built using mkColor(), intColor(), hsvColor(), or Qt's QColor class

+PlotItem.py - Graphics item implementing a scalable ViewBox with plotting powers.
+Copyright 2010 Luke Campagnola
+Distributed under MIT/X11 license. See license.txt for more infomation.
+
+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.
