Hi, I've been poking around with pcolor, trying to see what makes it tick, since its performance is biggest thing that drives me nuts about matplotlib. I do pcolor plots of weather radar data with ~100000 polygons in them. Unfortunately, these polygons are at best trapezoids, so I can't treat it as image data. With this data, pcolor takes ages to zoom and pan, even on my new workstaion. My end goal is to be able to use OpenGL to do some 2D rendering, since in my experience, this simply flies at rendering such data for interactive analysis.
I noticed that when I run the pcolor_demo.py (using current SVN trunk), 29396 separate calls are registered to RendererGDK->draw_path to simply draw the image the first time. Is there any reason why these can't be batched up and passed in one block to the renderer? This would make life easier in setting up OpenGL to render in one pass.
