I tried that - same results. I did continue to try different backends
- TkAgg lets me call figure(), pulls up an empty figure and then I call
plot(x,y) and the plot appears as expected. That backend is fine
with me, but I am wondering if I have found a bug or some sort of
interaction with GTK and / or wx. Here are snippets
from /etc/matplotlib/matplotlibrc (when it doesn't work)
backend : WXAgg
# if you are runing pyplot inside a GUI and your backend choice
# conflicts, we will automatically try and find a compatible one for
# you if backend_fallback is True
#backend_fallback: True
interactive : True
so I have interactive set.

Most likely, you were used to interactive mode being on. A new
installation of matplotlib might have over-written your matplotlibrc
file, resetting the option to False. Find your matplotlibrc file and
change interactive to True to get the behavior you want.I hope that helps!
