You are probably doing the best thing using wx for the event handling in this app, but you do not need to save to png. You can get access to the rendered figure in code as either a python buffer or string, using one of several *Agg backend methods, eg buffer_rgba, tostring_rgb, tostring_argb. See for example http://matplotlib.sourceforge.net/examples/pylab_examples/agg_buffer_to_array.html JDH ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
