I recently added to the ImageView class to make a live-updating GUI for a camera system. I needed to add markers to the histogram to show the 10th-90th percentile values. I did think by manually plotting points on the HistogramLUTITem's .plot attribute (PlotDataItem) .scatter attribute (ScatterPlotItem), and manually showing the scatter attribute. This was necessary since PlotDataItem only has a setData function for plotting, which clears the plot each time it is called (unlike the more standard PlotItem used in the examples).
Is this the only way to implement adding a plot to the HistogramLUTItem? If so, it seems worth replacing the PlotDataItem in the HistogramLUTITem with a PlotItem, since it would give more control over the histogram while adapting the ImageView class. -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
