If you are running interactively from the python shell, you need to
make sure "interactive" is set to True in your rc file and do not use
show.  

  http://matplotlib.sourceforge.net/faq.html#SHOW


Also, to work interactively, you must use either the tkagg backend or
a python shell that supports threading for the GUI you are using (GTK
or WX) such as ipython http://ipython.scipy.org, which has explicit
support for matplotlib in the pylab mode

  http://matplotlib.sourceforge.net/interactive.html

To test your installation, cd into the examples dir and try running
simple_plot.py from the unix shell.

  > cd examples
  > python simple_plot.py

  OR you can choose your backend from the shell with

  > python simple_plot.py -dTkAgg    
  > python simple_plot.py -dGTKAgg

If that works, almost surely you have an interactive problem that will
be cleared up with the links above.  If now, rerun the script with
--verbose-helpful and report back.

Good luck,
