Strange. pcolor_demo.py and pcolor_demo2.py work fine for me on linux
Try rm -rf site-packages/matplotlib and the 'build' dir of your
matplotlib install tree, and reinstall.
What, by the way, does it mean to "not work properly". Is this a
crash? Note an image interpolation bug was fixed in 0.63.0 which will
cause the axes limits to be a little different for imshow calls than
they were before. Earlier versions of matplotlib set the viewlim to
hide the edge artifacts, which no longer exist.
