[Matplotlib-devel] Changing rcParams locally, on the fly

[Phyks]

Ok, I was not expecting matplotlib to work this way. I was actually
thinking it was storing the drawing commands in some buffer, and was
actually doing the render when needed.

For my use case, I think I should better write a buffer on top of
matplotlib and only call it in the end, when I am actually drawing the
graph.

Thanks
