Hi,
When I do an errorbar plot (a.errorbar(), a = axis) with negative values and
then try to change the yscale to log (a.set_yscale('log')) matplotlib
crashes with:
Traceback (most recent call last):

I don't think this should be the expected outcome.. rather it should not
plot values that are illegal/negative (i.e. ignore them).
Is there a way I can get around this without having to search through my
data and remove points that are negative or NaN or INF when the yscale needs
to be log? That would also show an incorrect curve since a line would be
drawn across the points that were removed.. It should rather be gaps in the
line.
Thanks,
Soren
