matplotlib-users Mailing List for matplotlib

The matplotlib calendar claims there is a hangout today, but I can't find an invite on Google+. Am I missing something or was it cancelled?

Thanks Ben!
I was wondering if you can help me with a related question. How does
one change the artist for the legend? Since I have a "step" histogram,
it would be nice to have the legend display lines rather than outlined
rectangles.
Thanks,
Ted

mySensorArray = np.ma.masked_invalid(mySensorArray)
