- Added GraphItem class for displaying networks/trees
- Added ColorMap class for mapping linear gradients and generating lookup tables
(Provides gradient editor functionality without the GUI)
- Added ColorMapWidget for complex user-defined color mapping
- Added ScatterPlotWidget for exploring relationships in multi-column tables
- Added ErrorBarItem
- SVG and image exporters can now copy to clipboard
- PlotItem gets new methods: addLine, setLabels, and listDataItems
- AxisItem gets setTickFont method
- Added functions.arrayToQPath, shared between GraphItem and PlotCurveItem
- Added gradient editors to parametertree
- Expanded documentation, added beginning of Qt crash course
Bugfixes:
- Fixed auto-ranging bugs: ViewBox now properly handles pixel-padding around data items
- ViewBox ignores bounds of zoom-rect when auto ranging
- Fixed AxisItem artifacts
- Fixed GraphicsItem.pixelVector caching bugs and simplified workaround for fp-precision errors
- LinearRegionItem.hoverEvent obeys 'movable' flag
- Fixed PlotDataItem nan masking bugs
- Workaround for segmentation fault in QPainter.drawPixmapFragments
- multiprocess and RemoteGraphicsView work correctly in Windows.
- Expanded python 3 support
- Silenced weave errors by default
- Fixed " 'win' in sys.platform " occurrences matching 'darwin' (duh)
- Workaround for change in QImage API (PyQt 4.9.6)
- Fixed axis ordering bug in GLScatterPlotItem
- GraphicsItem.pixelVectors copies cached results before returning
- Multiprocess fixes for Windows:
- mmap/shm uses anonymous maps rather than tempfiles
- avoid use of getppid and setpgrp
- work around hmac authentication bug (use os.urandom to generate key)
- AxisItem shows fewer tick levels in some cases.
- Lots of boundingRect and dataBounds caching
(improves ViewBox auto-range performance, especially with multiple plots)
- GraphicsScene avoids testing for hover intersections with non-hoverable items
(much less slowdown when moving mouse over plots)
Improved performance for remote plotting:
- reduced cost of transferring arrays between processes (pickle is too slow)
- avoid unnecessary synchronous calls
Added RemoteSpeedTest example
- fixed example testing script
- Added finer axis ticks back in some instances
- fixed improper bounds caching in log/fft mode
- fixed exception handling in remoteproxy
- AxisItem shows 2 tick levels instead of 3
- Lots of boundingRect and dataBounds caching
(improves ViewBox auto-range performance, especially with multiple plots)
- GraphicsScene avoids testing for hover intersections with non-hoverable items
(much less slowdown when moving mouse over plots)
These are deep changes; need good testing before we release them.
