But you can easily rewrite your function to use the Agg backend as in http://matplotlib.sourceforge.net/examples/api/agg_oo.html the agg backend will detect other extensions, like png, pdf, svg or ps and do the right thing. So if you'd like to resubmit this as an svn patch that doesn't use pyplot, I think it would be a useful addition. http://matplotlib.sourceforge.net/faq/howto_faq.html#contributing-howto JDH -- Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.
