Legend with Multiple plots about corner.py HOT 5 CLOSED

Thanks for the suggestion, Kyle.

I was able to do it with

import matplotlib.lines as mlines

blue_line = mlines.Line2D([], [], color='blue', label='SGM')
red_line = mlines.Line2D([], [], color='red', label='GMM')
fig = corner(samples, color = 'b')
corner(samples1, color = 'r', fig=fig)

plt.legend(handles=[blue_line,red_line], bbox_to_anchor=(0., 1.0, 1., .0), loc=4)

This does attach the legend to the last plot in the figure (the bottom right histogram) so I moved it out of the plot and into the empty space.

from corner.py.

I don't know of a simple way.

You should be able to use fig.legend as in this example: http://matplotlib.org/examples/pylab_examples/figlegend_demo.html

However, you need a handle to the lines in the plot for that. If you can't pull these out of the figure object, you could use a proxy artist.

from corner.py.

Nice! Can you paste in the resulting plot so we can take a look at your
handiwork, please? Thanks!

Sure thing!

Alright! Very nice :-) The only design choices I might suggest would be to
center the legend in the blank panel (both horizontally and vertically) and
remove the box around it. I guess at least sometimes one would also want to
legend the truth point as well.
