Bugfixes: - ArrowItem auto range now works correctly - Dock drag/drop fixed on PySide - Made padding behavior consistent across ViewBox methods - Fixed MeshData / python2.6 incompatibility - Fixed ScatterPlotItem.setSize and .setPointData - Workaround for PySide bug; GradientEditor fixed - Prefer initially selecting PlotItem rather then ViewBox when exporting - Fixed python3 import error with flowcharts Cleaned up examples, made code editable from example loader Minor documentation updates
Features:
- 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
Plotting performance improvements:
- 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
Documentation: - Added documentation on export system - Added flowchart documentation and custom node example Bugfixes: - prevent PlotCurveItem drawing shadow when unnecessary - deprecated flowchart.Node.__getattr__ -- causes too many problems.
Bugfix: prevent adding invalid entry to sys.path when running examples
Bugfixes: - SVG export text elements use generic font-family as backup, corrected item transformation issues - Fixed RuntimeError caused when clearing item hierarchies from ViewBox - Fixed example execution bug Packaging maintenance: - Added missing files to MANIFEST.in, fixed setup.py package detection - Added debian control files for building source packages - Fixed version numbering in doc, __init__.py
