What about x and y axis? None of your examples above have x/y axis --
instead they have frames. Most of the code your suggesting deleting
is about drawing x/y axis, but none of your examples have them, and I
don't know how to draw them using matplotlib. Maybe there is some
easy way to do this by repositioning the axis?
It is fine in my opinion to tie axes more closely to matplotlib,
insofar as matplotlib actually has the functionality.
