Hi Danny,
I think I know what's going on here - The rendering of bar-ends was chang=
ed at one point to use tick line markers instead of being rendered as par=
t of the line. I had seen the behaviour you describe at one point, but fo=
r some reason (brain failure!) had convinced myself later that the behavi=
our had remedied itslef somehow. I didn't understand this at the time, bu=
t I should have put the effort in because it's crept through and you've t=
ripped over it. The solution is to revert the bar-end rendering to the wa=
y it used to be done. I don't know if you can fix this without touching t=
he Matplotlib source since I suspect the line markers reference isn't bei=
ng returned. I can't look at this for a day or more, so either be patient=
and I'll post the fix to this list, or maybe John Hunter will get to it =
first,
regards,
Gary Ruben
