[Matplotlib-users] Caching of canvas or canvas data?

[Neil P. <mat...@ke...>]

Hi,

I've developed a GTK application under linux (debian etch) which plots 
my simulation data really nicely. I'm now trying to implement some 
caching to avoid a) loading datafiles which are 'recent' and b) 
replotting and redrawing data which is 'recent' (assuming this would be 
quicker!). I have managed the former rather easily using a fifo type 
structure, and the latter could be easy if I had some idea how to cache 
the buffer, pixels or whatever is most convenient of the canvas. For 
example, could I have multiple canvases, and switch which one is 
displayed in the gtk container? or would it be better to save the 'data' 
(pixels? vector graphics?) of the canvas somewhere, and copy that 
backwards and forwards? Any ideas?

Thanks,
