* Emit signal when GraphicScene.addItem() is used
Emit a signal (sigItemAdded) just after adding an item to a scene.
The item object is emited as the only signal argument.
This signal is useful for code that may want to react to newly added
items of a plot.
* Emit signal when GraphicScene.removeItem() is used
Emit a signal (sigItemRemoved) just after removing an item from a scene.
The item object is emited as the only signal argument.
This signal is useful for code that may want to react to removed
items in a plot.
* [SVGExporter] Fix width and height
* [SVGExporter] Fix background color
* [SVGExporter] Remove f-strings
* [Exporter] Fix for QtGui.QGraphicsScene
* Revert "[Exporter] Fix for QtGui.QGraphicsScene"
This reverts commit 5bdd25ea40.
* [test_svg] Fix unit test
* Permit nan, inf, and -inf for float SpinBox
Bounds are enforced against inf and -inf inputs, but not for nan.
* Ensure SpinBox text is updated when out-of-bounds value is entered
* Make inf and nan entry in SpinBox case-insensitive
* Make SpinBox example behave as advertised
* Make non-finite SpinBox values optionally allowed
* Python 2 compatibility
The three parameters "shape, vectors, origin" can't be passed as parameters because they are computed, which raise an error when kwds is passed to affineSlice.
- Parameters now respond to title change in setOpts
- Add Parameter.title()
- Action parameter uses default name/title handling in addition to setting button text (fixes#1320)

This commit adds a depth buffer in renderToArray().
This fixes the issue that overlapping objects are rendered incorrectly
when using renderToArray() on a GLViewWidget.
This might be related to issue #743.
* Add "lstep" and "rstep" step Modes
stepMode is currently either True or False. If it is True,
it requires the user to make len(x) = len(y)+1. This is
inconvenient because it makes it difficult to change the
stepMode on a given curve (just as one would change, e.g.,
its color).
This commit extends the current situation by introducing
two more step modes: "lstep" and "rstep", which do not require
passing an extra x value. In turn, this modes associate each
y value to either the left or the right boundary of the step.
For example, the "rstep" mode is handy when plotting "life"
digital signals in which x,y data pairs are appended as they
are read.
This commit does not modify the behaviour in case of stepMode=True
* Replace step mode names: lstep,rstep -> left,right
* Improve docs for stepMode
Reword docstring and add it to PlotDataItem class too
* Document left and right stepModes as added in v 0.12.0
TODO: confirm the exact version number to use here
* Add comments stress the need for "is True"
Some conditional statements in the code regarding stepMode are
done with "is True". This is actually required since other
possible values such as "left" also evaluate as true but should
not be caught.
* Deprecate boolean API for stepMode
Introduce stepMode="mid" as a replacement of stepMode=True,
but keeping full backwards compatibility with the old API.
Adapt docs, examples and tests accordingly.
* Raise ValueError on unsupported stepMode values
* Rename "mid" step mode to "center"
* Remove "added in 0.12.0" note
See https://github.com/pyqtgraph/pyqtgraph/pull/1360#discussion_r502746919
* Add deprecation warning when stepMode=True
Issue a DeprecationWarning if stepMode=True is being passed to the
constructor or setData() of PlotDataItem or PlotCurveItem.
Note: warnings module is imported locally so that it is esier to
remove once this check is no longer needed.
* Fix wrong syntax in last commit
Fix usage of "default" kwarg in dict.get()
* SignalProxy: Correct initialization without slot argument and provide tests
* Add missing slot is None case on disconnect
* Start new tests
* Exception block
* Test no module
* Different signal
* Debugging the signal connect
* Re initialize proxy after disconnect
* Add more test cases for blockSignal
* Change test case for signal count
* Give up for python 2 and pyside
* Exclude for Python 2.7 and PySide
* Convert float to integers in timer start period
This is something we're overriding in Orange3 (biolab/orange3#5007), as we change the symbols' alpha_value to show selected symbols. The default + and x symbols are too thin to show a noticeable change in alpha_value.
But I thought you might agree that the symbols look nicer this way.
* Fix PlotItem.setAxisItems
- Use extend so visibleAxes remains a flat list.
- More robust logic for detecting adding an AxisItem instance to
mulitple plots and suggest a workaround in the error message.
* Simplify membership check
* Add test for PlotItem setAxisitem logic
