Hi, Unfortunately, the current legend frame work does not support errorbars. And I don't think implementing this is easy. The thing is that errorbar creates multiple artists instead of single one.
The best workaround I can think of is to make the legend only with markers (and lines if you want), without errorbars. The return value of the errorbar command is a length 3 tuple, where the first element is a line2d instance for markers (and lines connecting markers). http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.errorbar Thus, something like below will work. legend([eb1[0],eb2[0]],['0.00001','0.0001'],numpoints=1) -JJ On Tue, Mar 31, 2009 at 11:02 AM, Wendell Cropper <wcrop...@ufl.edu> wrote: > > Hi, > > This script will not show the correct symbol in the legend for any errorbar > plots after the first one.
