Matplotlib error at xu.analysis.sample_align.area_detector_calib #124

Closed azkhadiev closed 3 years ago

It seems that there are an error if one uses xu.analysis.sample_align.area_detector_calib with debug = True

Its true that i did not run this code with the debug flag on for a long time. I always hoped to completely rewrite this part but never came to it. The mentioned commit should fix the reported issue. Please report back if there are other issues.
