I have a GTK app which runs its matplotlib stuff in a separate

I would like to pop up a new top-level window for each figure.
How do I do that?  My current build-a-plot code looks like this:

   figure = pylab.figure()
   ax = figure.add_subplot(111)
   ... build dates and prices lists ...
   ax.plot(dates, prices)
   formatter = matplotlib.dates.DateFormatter('%H:%M:%S')
   ... what goes here? ...

Instead of show() or draw() as the last line what should I be

Which version of matplotlib are you using?  There have been numerous improvements to interactivity and multiple calls to show() in version 1.0 and beyond.

There might still be some issues with multiple gui event loops that I think is currently being addressed by the ipython group.  Maybe someone else here might be more knowledgeable about that.

I hope that helps!
