I’ve installed matplotlib in a virtual environment but am having a problem with generating a plot.
I’ve tried to run a “simple_plot.py” both as a script and from within the ipython/python shell.
I’ve changed the backend in virtualenvs/…/lib/python2.6/site-packages/matplotlig/mpl-data/matplotlibrc
from the within the virtualenv (regular python) shell I can:
(and the test window opens as expected)
My virtualenv sys.path includes: "/home/virtualenvs/…/lib/python2.6/lib-tk’
When I try to use ipython -pylab (or run a script) I’m getting an error:
… import _tkagg
ImportError: No module named _tkagg
I’m assuming that there’s a relatively simple fix for this related to the “matplotlibrc” backend but can’t for the life of me work out how to get it fixed. I’d be grateful for any help.
