This is really a question for the matplotlib list, but here's a short 

Matplotlib can use a number of "back-ends". These are the parts that do 
the actual rendering. The some of the options are:

TkInter, pyGTK, wxPython, Agg, pyQT, PDF, PS, etc.

The default back end is set in your .matplotlibrc file. Alternately, you 
can set it at runtime like so:

import matplotlib

then you can do

import pylab

etc, and tk will be used.

The examples can be downloaded as a zip file from the main MPL web site:
