Answer 1

When the legend doesn't work out you can always make your own easily like this:

import matplotlib

name_to_color = {
    'Expected':   'green',
    'Provided':   'red',
    'Difference': 'blue',
}

patches = [matplotlib.patches.Patch(color=v, label=k) for k,v in name_to_color.items()]
matplotlib.pyplot.legend(handles=patches)
