Hi, I create (for quick testing and prototyping) some matplotlib windows from my segmenteditor effect (in the callback of the apply button) like described here:

Setup: pip\_install("matplotlib wxPython") Example interactive plot using matplotlib: # Get a volume from SampleData and compute its histogram import SampleData import numpy as np volumeNode = SampleData.SampleDataLogic().downloadMRHead() histogram = np.histogram(arrayFromVolume(volumeNode), bins=50) # Set matplotlib to use WXAgg backend import matplotlib matplotl…
Unfortunately, it is not possible to close the window after use. Any ideas why this happens? Thanks.

You can find various ways of plotting using matplotlib here: [https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Using\_matplotlib](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Using_matplotlib) (including rendering in a static qt window, which can be surely closed without problems).
