Re: [Matplotlib-users] avoid duplicate legends

[Benjamin R. <ben...@ou...>]

Legends entries are blindly constructed. Each plotting call that has a
legend keyword argument will produce a legend entry if you are
automatically building the legend. You can pass a label value of
"__nolabel__" to prevent an entry if you know you are about to do something
that would duplicate the entries. Another approach is to manually collect
unique artists and manually build the legend (I think there is an example
of that in the gallary).

As for configuring the legend, there are a bunch of parameters that can be
set for sizing the font. I think the sizing of the marker is determined by
their size in the plot, though.

Cheers!
