Hi there I found that the error is related to legend! If I disable
self.plotaxes.legend(bbox_to_anchor=(0.95, 0.95), loc=2, prop=FontProperties(size='small'),numpoints=1) I can change the linestyles and it works like a charm, but if I turn on that line again... just errors. can anyone think of something? best Carlos On Wed, Apr 28, 2010 at 09:46, Michael Droettboom <md...@stsci.edu> wrote: > I can't reproduce the error on 0.99.
