of polygons, circles, ellipses I draw, as well as to using different colors and
sizes. I don't even know how to start debugging this.
One step forward, though, is that I checked running the script directly from
python, instead of within ipython, and it is running as it should. This is with
more than 300 thousand ellipses, whereas within ipython it stops working with as
little as 2 thousand ellipses.
I am running both matplotlib and ipython development trees.
Any expert on how events work out there? And mpl-inpython interaction?
Thanks for any hints/suggestions.
Hmm, interesting observation. There is very little in mpl that limits your ability to produce elements for plotting (which is probably why you were getting shrugs from the mailing list...). However, ipython has various "tricks" for caching mpl elements, and can sometimes be a bit excessive in memory usage. This could lead to some issues.
Now that you have identified ipython as the culprit, I would suggest taking this to the ipython list and seeing if they can better identify the problem for you.
