Legend with Multiple plots

Hello,

I have two corner plots that I overlay using the fig=fig keyword. It is only with two parameters and I wanted to add a legend in the empty corner. One plots the contours blue and the other one plots red. Is there a simple way to do this with corner.py?

Thank you, Kara

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.

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.
