Setting color of Circle Patch in matplotlib?

Question

Setting the color or a Circle patch directly is not supported through class methods as we might assume;

circle.set_color('b') 

^^ this is incorrect.

Answer 1

Patches have two distinct colors, facecolor and edgecolor , which you can set by, respectively c.set_facecolor(...) (or set_fc ) and c.set_edgecolor(...) (or set_ec ).

The setp machinery is just a convince method for looking up these functions. setp(artist, key=val) does, more-or-less getattr(artist, "set_%s" % key)(val) .
