I'll bet dollars to donuts you are running matplotlib inside an IDE,
eg Idle, PythonWin, Scintilla, etc.  Quoting from
http://matplotlib.sourceforge.net/installing.html

  Important: There are known conflicts with some of the backends with
  some python IDEs such as pycrust, idle. If you want to use
  matplotlib from an IDE, please consult the backends documentation
  for compatibility information. You will have the greatest likelihood
  of success if you run the examples from the command shell or by
  double clicking on them, rather than from an IDE. If you are
  interactively generating plots, your best bet is TkAgg from the
  standard python shell.

The "backends" page, referred to above, is at
http://matplotlib.sourceforge.net/backends.html.  Basically, you
should open up a command shell and try to run one of the examples from
the matplotlib src distribution (the *.zip file for windows users);
Eg,

  c:\matplotlib\examples> python simple_plot.py

if this works fine (my guess is it will), then you'll know you have an
IDE problem and not a matplotlib specific problem.  Unfortunately,
this problem tends to crop up a lot.  See for example
http://sourceforge.net/mailarchive/message.php?msg_id=8610351 and the
responses to that post for more information


Let me know if this is the case.
