Hi all,
I'm wondering why using shadow=True causes shading of the legend box when
framealpha is set to a number. That is, if I do:
fig,ax = plt.subplots()
ax.plot(x,y1,label='y1')
ax.plot(x,y2,label='y2')
ax.legend(framealpha=0.5,shadow=True)
The face color of the legend is gray. There doesn't seem to be any reason
for this, so I'm assuming it's a bug. I've been looking through the docs
and haven't found anything relevant - and haven't found any way around it
other than turning off the shadow. Any help would be appreciated.
Regards,
Jon

Jon,
I think with the transparent legend face, you're seeing the dark shadow
underneath it. This seems to be reflected when changing the alpha
values.The shadow itself if is a polygon the same size of the legend,
z-ordered below the legend itself, and offset slightly.
Does that explain this to you?

Ah, yes that makes sense. Though I would still say that the intention of
having the shadow is to have at the edges and the method of using the
polygon in that way is a simple method to get it. Unfortunately the side
effect of that is to cause that graying of the face of the legend when
transparency is used. Seems like it would not be an easy fix.
