legend with proxy artists


I read the legend guide, so when I did this:

ax.legend([Circle((0,0),1,fc=‘red’)], [‘red circle’])

I expected the symbol in the legend to be a red circle, but got a red rectangle. In fact, no matter what artists I pass in as the first argument, the legend shows rectangles (the colors are correct, though). Why?
