I don't think so. This back-end is only usable to produce files, it
can't be used for interactive sessions (which is the key appeal of the
numpy/scipy/matplotlib work-flow over C/C++). IMO we should switch to
the TkInter back-end which is part of the standard Python Library. It
was not available in our python when I did package matplotlib.

Hi Guix,
the attached patch adds python{,2}-statsmodels to statistics.scm. Note
that this depends on my previous patch adding patsy to the same module.

Hmm I lost track of patsy in my inbox. I’ll check afterwards.

This looks good. Should we eventually change Matplotlib itself to use
this back-end by default? What’s at stake exactly?
Thanks!
