Re: [Matplotlib-users] Histogram with single series - colour coding different ranges?

[Victor H. <vic...@ya...>]

Goyo,

Aha, so I can call .set_facecolor() on the Patch objects, and then force the
graph to re-draw().

I've tested it - it works when I do savefig(). And if I'm running it
interactive, I just run matplotlib.draw() after modifying the patch list.

I suppose I can combine that technique with the calculation tip from Ben to
colour-code the different region.

I could run a for-loop over the Patch list, and do multiple if's - however,
wondering if there's a way to do it with a list-comprehension?

Thanks for the tips, guys =).

Cheers,
Victor
