[yt-users] matplotlib backend install

[Nathan Goldbaum]

For you first issue, that's actually the expected behavior, since
PlotCollection uses the non interactive Agg backend behind the scenes.  You
might have more luck with PlotCollectionInteractive

Not sure what's going wrong with iyt.  For what it's worth, I believe iyt
is the same as doing "from yt.mods import *" inside a running IPython
session.  It may also import pylab, but that can be set up by invoking the
%pylab magic in IPython.
