ImageItem.getHistogram is more clever about constructing histograms:
- integer dtype images now have integer-aligned bins, with bin number
determined by a target value
- step size is automatically chosen based on a target image size
- bins and step arguments have default values 'auto'
- integer dtype images now have integer-aligned bins, with bin number
determined by a target value
- step size is automatically chosen based on a target image size
- bins and step arguments have default values 'auto'
When an ImageItem's data has an integer dtype, this patch ensures that
each bin of the LUT histogram contains the same number of integer
values, in order to avoid "spikes" in the histogram that are merely due
to some bins covering more integer values than others.
This commit needs testing (it was rebased from an old commit).
- 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
This merge converts all absolute imports into relative imports throughout pyqtgraph.
This allows pyqtgraph to be embedded as a sub-package of larger packages.
- 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
* __init__.py now contains latest release version string
* installing from git checkout that does not correspond to a release commit
will result in a more descriptive version string
New Profiler class from Antony Lee:
* Simpler API (with backward compatibility)
* Individual Profilers can be enabled by environmental variable PYQTGRAPHPROFILE
* Loads only data that is currently visible
* Downsamples to avoid plotting too many samples
* Loads data in chunks to limit memory usage during downsampling
