There is some preliminary work to wrap matplotlib figures in Graphics
objects, so you could do:
Graphics(pylab.plot(...))
and Sage would treat it like any other Sage graphics object (i.e., you
could add it to other things, etc.)
See http://trac.sagemath.org/sage_trac/ticket/5128
There is still a problem with the posted patch which I'm sure would be
easy for someone familiar with matplotlib to fix. If you know how (or
if anyone knows how) to get the min/max x-coordinates and the min/max
y-coordinates of generic matplotlib figure/object/whatever would be
passed in, that is what is still needed.
