[Matplotlib-users] figlegend

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

S=E6l !

I have installed matplotlib-0.52 and succesfully ran the figlegend example.
However when I try to run it directly in my program into a figure i am not =
as successful:
- I can create the legend with=20
leg=3Dmatplotlib.matlab.figlegend(tuple([i[1] for i in d]),tuple([i[0] for =
i in d]),'upper center')
leg.draw()
But it does not appear anywhere

If I try to call figlegend from the canvas, canvas.Figure or canvas.Figure.=
axes[0], I get an erro message as figlegend is not defined in any of these =
contexts
	canvas.figure.figlegend(tuple([i[1] for i in d]),tuple([i[0] for i in d]),=
'upper center')
	AttributeError: Figure instance has no attribute 'figlegend'

How can I get my figlegend to appear in my window ?
