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) - ComboBox will raise error when adding multiple items of the same name 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 - 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 - Added Flowchart.sigChartChanged - 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.
