matplotlib-users Mailing List for matplotlib

I believe the issue is still a bug. I have recently begun working with
pylab. With the latest release, I get the same error when I execute the
vertical_ticktabels.py example.
The error message is: "TypeError: list indices must be integers"=20

Thanks for the info. Nothing jumps at me, but I was mostly providing you with 
pointers on what kind of info may help John, who is the one who actually knows 
that code. I've only bumped into the problem (which he has never found on a 
machine he works on) and failed to produce any kind of solution. Let's hope 
some of this flips a switch for him.
Cheers,

I'm struggling with trying to learn python, QT, pyqt, and matplotlib
all at the same time...
It would be very helpful for me if someone could modify the 
embedding_in_qt.py to include NavigationToolbar2. I've
been trying to get this to work all day, and am just about
worn out...
Thanks!!
