This info may or may not be useful. If I save a plot with savefig()
without specifying a figsize, sometimes the figure gets clipped. What
gets saved is the portion of the image that show() displays. I
determined experimentally that figsize=(13,10) causes show() to open the
image at full screen size and so far using that size saves an unclipped
image.
