[Matplotlib-users] backend for matplotlib on NAS Lou (Thomas Caswell)

[Slavin, Jonathan]

Just thought I report that I did get matplotlib working as desired on Lou.
It turns out that using the version of matplotlib and ipython that's loaded
by pkgsrc works (i.e. module load pkgsrc), if you set the backend to Qt4Agg
or GtkAgg in your matplotlibrc.  In my case I had to remove from my path
the anaconda distribution that I had installed.  I was also able to install
yt using pip (with the --user argument so it installs under ~/.local).

Regards,
Jon
