[Matplotlib-users] dynamic image demo: suggestions sought

[Andrew S. <str...@as...>]

Hi plotters,

I've shamelessly modified dynamic_demo_wx.py to create 
dynamic_image_wxagg.py, attached.  This is my initial attempt to get 
matplotlib to dynamically update images.  Basically it all works 
hunky-dory except 1) an apparent memory leak and 2) flicker when I run 
this in linux (haven't tested other OSes).  I offer #1 to John or other 
memory-leak hunters out there and ask if any WXpert can address #2.  
I've googled a bit and it appears the WX backend (from which WXAgg is 
derived) does the Right Thing and calls wxClientDC on a non-OS generated 
redraw request, which is supposed to reduce or eliminate flicker.  The 
other tip is to catch EVT_ERASE_BACKGROUND, which I've also done to no 
apparent improvement. Thus, I ask for help -- any suggestions on how to 
eliminate this flicker?

John -- feel free to stick this in examples if you think it's worthy.

Cheers!
Andrew
