# Credit: Original .travis.yml lifted from VisPy

# Here we use anaconda for 2.6 and 3.3, since it provides the simplest
# interface for running different versions of Python. We could also use
# it for 2.7, but the Ubuntu system has installable 2.7 Qt4-GL, which
# allows for more complete testing.

pyqtgraph-0.9.9

API / behavior changes:
- Dynamic import system abandoned; pg now uses static imports throughout.
- Flowcharts and exporters have new pluggin systems
- Version strings:
- __init__.py in git repo now contains latest release version string
(previously, only packaged releases had version strings).
- installing from git checkout that does not correspond to a release
commit will result in a more descriptive version string.
- Speed improvements in functions.makeARGB
- ImageItem is faster by avoiding makeQImage(transpose=True)
- ComboBox will raise error when adding multiple items of the same name
- ArrowItem.setStyle now updates style options rather than replacing them
- Renamed GraphicsView signals to avoid collision with ViewBox signals that
are wrapped in PlotWidget: sigRangeChanged => sigDeviceRangeChanged and
sigTransformChanged => sigDeviceTransformChanged.
- GLViewWidget.itemsAt() now measures y from top of widget to match mouse
event position.
- Made setPen() methods consistent throughout the package
- Fix in GLScatterPlotItem requires that points will appear slightly more opaque
(so you may need to adjust to lower alpha to achieve the same results)

New Features:
- Added ViewBox.setLimits() method
- Adde ImageItem downsampling
- New HDF5 example for working with very large datasets
- Removed all dependency on scipy
- Added Qt.loadUiType function for PySide
- Simplified Profilers; can be activated with environmental variables
- Added Dock.raiseDock() method
- ComboBox updates:
- Essentially a graphical interface to dict; all items have text and value
- Assigns previously-selected text after list is cleared and repopulated
- Get, set current value
- Flowchart updates
- Added Flowchart.sigChartChanged
- Custom nodes may now be registered in sub-menu trees
- ImageItem.getHistogram is more clever about constructing histograms
- Added FillBetweenItem.setCurves()
- MultiPlotWidget now has setMinimumPlotHeight method and displays scroll bar
when plots do not fit inside the widget.
- Added BarGraphItem.shape() to allow better mouse interaction
- Added MeshData.cylinder
- Added ViewBox.setBackgroundColor() and GLViewWidget.setBackgroundColor()
- Utilities / debugging tools
- Mutex used for tracing deadlocks
- Color output on terminal
- Multiprocess debugging colors messages by process
- Stdout filter that colors text by thread
- PeriodicTrace used to report deadlocks
- Added AxisItem.setStyle()
- Added configurable formatting for TableWidget
- Added 'stepMode' argument to PlotDataItem()
- Added ViewBox.invertX()
- Docks now have optional close button
- Added InfiniteLine.setHoverPen
- Added GLVolumeItem.setData
- Added PolyLineROI.setPoints, clearPoints, saveState, setState
- Added ErrorBarItem.setData

Bugfixes:
- PlotCurveItem now has correct clicking behavior--clicks within a few px
of the line will trigger a signal.
- Fixes related to CSV exporter:
- CSV headers include data names, if available
- Exporter correctly handles items with no data
- pg.plot() avoids creating empty data item
- removed call to reduce() from exporter; not available in python 3
- Gave .name() methods to PlotDataItem, PlotCurveItem, and ScatterPlotItem
- fixed ImageItem handling of rgb images
- fixed makeARGB re-ordering of color channels
- fixed unicode usage in AxisItem tick strings
- fixed PlotCurveItem generating exceptions when data has length=0
- fixed ImageView.setImage only working once
- PolyLineROI.setPen() now changes the pen of its segments as well
- Prevent divide-by-zero in AxisItem
- Major speedup when using ScatterPlotItem in pxMode
- PlotCurveItem ignores clip-to-view when auto range is enabled
- FillBetweenItem now forces PlotCurveItem to generate path
- Fixed import errors and py3 issues in MultiPlotWidget
- Isosurface works for arrays with shapes > 255
- Fixed ImageItem exception building histogram when image has only one value
- Fixed MeshData exception caused when vertexes have no matching faces
- Fixed GLViewWidget exception handler
- Fixed unicode support in Dock
- Fixed PySide crash caused by emitting signal from GraphicsObject.itemChange
- Fixed possible infinite loop from FiniteCache
- Allow images with NaN in ImageView
- MeshData can generate edges from face-indexed vertexes
- Fixed multiprocess deadlocks on windows
- Fixed GLGridItem.setSize
- Fixed parametertree.Parameter.sigValueChanging
- Fixed AxisItem.__init__(showValues=False)
- Fixed TableWidget append / sort issues
- Fixed AxisItem not resizing text area when setTicks() is used
- Removed a few cyclic references
- Fixed Parameter 'readonly' option for bool, color, and text parameter types
- Fixed alpha on GLScatterPlotItem spots (formerly maxed out at alpha=200)
- Fixed a few bugs causing exit crashes

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.
