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

[Jae-Joon L. <lee...@gm...>]

You may consider to use proxy artists.

plot([1,2,3], "s-")
plot([1,3,2], "d-")

l1 = Line2D([0], [0], marker="s", color="k")
l2 = Line2D([0], [0], marker="d", color="k")

p1 = Rectangle((0, 0), 1, 1, fc="b", ec="none")
p2 = Rectangle((0, 0), 1, 1, fc="g", ec="none")

legend([p1, p2, l1, l2], ["color1", "color2", "s", "d"], ncol=2)

There is no easy way to use text itself as the legend handles, and
this will need some more tweaks.
If you do need this, I'll try to come up with some example.
