Figure legend doesn't properly treat errorbars

[smithsp]

Consider:

from pylab import *
x = arange(0,1,.01)
y = x**2
fig = figure(2)
ax = fig.add_subplot(111)
errorbar(x,y,yerr=x/10.,label='$x^2$')
errorbar(x,y**3,yerr=x/10.,label='$x^6$')
legend(loc='upper center')
h,l = ax.get_legend_handles_labels()
fig.legend(h,l,loc='lower right')

I am getting the right legend for the axes based legend, but the figure based legend seems to be using the different parts of the errorbar for subsequent handles, instead of using them as a group.

I believe I fixed this with 1d6b55d.

For reference, here are some workaround you can try (this was originally posted on the mailing list)

from matplotlib.legend import Legend
l = Legend(fig, h, l, loc='lower right')
fig.legends.append(l)

This should be equivalent to fig.legend(h,l,loc='lower right').

Or, if you don't need axes legend, you may do

legend(h,l,loc='lower right', bbox_to_anchor=[0,0,1,1],
      bbox_transform=fig.transFigure)

JJ,

Thank you. I did get the original post to the list, and I did verify that the workaround works (I even replied to the list, but perhaps it didn't make it.)

Thanks,
Sterling
