[Matplotlib-users] How can I customize a legend?

[Jeremy C. <jlc...@gm...>]

I have a plot that I need to add a customized legend.  (The plot is
attached to this email.)  I want to show that each color represents
something as well as each marker symbol.  For example:

Green -> a                      Square  -> j
Blue   -> b                      Circle    -> k
Red    -> c                      Triangle -> l
Black ->  d                      Diamond -> m


When representing the color, the symbol doesn't matter and vice versa
for representing the symbol.  Is there an easy way to do this or do I
have to write some checks into my plotting function to make this
happen.

Thanks,
Jeremy
