Return images with matplotlib?

[Jan Danielsson]

Hello all,

   I have written a program which takes some data from a postgresql
database, and via mod_python outputs it as tables on a web site. Now I
would like to present these tables as graphs, which matplotlib can do.
  But in order to properly display these graphs on the web page, I need
to return the image data, like so:

def barchart(req, params):
   some_format = matplotlib.generate_fancy_graph(params)
   png_buf = make_png_buffer(some_format)
   return png_buf

   Is this possible? If so -- how?
