pyqtgraph-0.9.9 [unreleased]
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)
New Features:
- New HDF5 example for working with very large datasets
- Added Qt.loadUiType function for PySide
- Simplified Profilers; can be activated with environmental variables
- Added Dock.raiseDock() method
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
