A few weeks ago there was a discussion about putting scatter symbols in
the legend (see
http://www.nabble.com/Show-shapes-on-scatterplot-legend--to15744380.html).
I would like to implement scatter symbols in the legend, but I am having
some problems doing so. In the function _get_handles in legend.py, the
symbol can be placed in the legend by doing something like:
for path in handle._paths:
xy = path.vertices
p = Polygon(xy)
The problem is that the polygon that gets drawn is the wrong size and
aspect ratio. It would seem that this would call for some sort of
scaling or transform to make the symbol the proper size, but I need some
assistance or a pointer to documentation on how to do this.
Thanks,
Paul Novak
