[Matplotlib-users] How avoid black borders/padding of colored rectangles in pcolor plots?

[<seb...@sp...>]

Attached is a pcolor plot made with Matplotlib.

I have lots of rectangles of different colors which
Matplotlib created wonderfully which was exactly
what I was trying to do.

(I have 400 rectangles across the plot in horizontal
direction.)

It appears there are small black borders (padding?) to all little
colored rectangles that make the plot appear more
choppy and less 'blended' in color than I would prefer.
It may be that I *must* have more rectangles to make
these black borders be invisible.

I was wondering if there is any way I can remove
thin black lines (borders) in this plot for cases
like this where I don't have zillions of rectangles
to make black lines too small to notice.

Chris

Does the docstring for pcolor help?

      * shading = 'flat' : or 'faceted'.  If 'faceted', a black grid is
        drawn around each rectangle; if 'flat', edge colors are same as
        face colors

Try

pcolor( your_other_args, shading='flat')

Cheers!
