[Matplotlib-users] Can't override matplotlibrc ?

[Gary P. <pa...@in...>]

It seems that I can't completely override my choice of backend.

E.g.,  I have set TkAgg as my default back end.  Yet if I modify
examples/anim.py to include matplotlib.use('GTKAgg') or
matplotlib.use('GTK') it will not run.  A window appears, but it contains a
static, non-changing graph.  To run anim.py, I have to modify matplotlibrc.
Same behavior the other way:  with GTKAgg selected in matplotlibrc, I can't
run Todd's anim_tk.py, even with TkAgg selected in the script.   Am I doing
something stupid?
