I understand why things were not behaving as I expected and I don't really
have any good ideas on how to make a legend from a RegularPolyCollection in
general.
However, I do not grok why fill_between returns a RegularPolyCollection
rather than a Polygon (like fill does). Does fill_between(x,y0,y
i can't make a legend for a fill_between and don't understand what i'm doing
wrong. the following code seems like the most obvious way to make a legend
for a fill_between, but does do what i expect. the code plots, but
complains that "No labeled objects found." any help would be much
appreciate
