Hi everybody

When I tried to import matplotlib from the Python version that is
bundled with Sage, I found that the moduled tkagg was not present.

  >>>  import matplotlib.pyplot as plt
  >>>  No module named _tkagg

Would anybody tell me how to install this module in the Python version
of Sage. I am using Debian/GNU Linux and Sage 4.3.5

Thanks a lot in advance!

Jose.

Hi,

As I recall, you need to set an environment variable before building
matplotlib. In bash:
$ export SAGE_MATPLOTLIB_GUI='yes'

You will also need the dev pakages installed.
$ sudo apt-get install tk-dev tcl-dev

After installing the dev packages you should only have to reinstall
matplotlib.
$ sage -f matplotlib

Dear Adam,

Absolutely fantastic, I just followed your instructions and Matplotlib is working under my Sage.

Thanks a lot

Jose.
