Re: [Matplotlib-users] why legend does not show in matplotlib-1.2.1 & py2.7

[Paul H. <pmh...@gm...>]

Sorry I have to be so brief, but just like the error says, you fed the
legend function the wedges returned by the pie command. But legend can't
handle wedges. As the proxy artist tutorial hints, you need to feed it
rectangles created manually (i.e., outside of any plotting commands).

Hope that gets you started,
