I'm not familiar with the package naming scheme used below. What OS is this on? > > So, the compile dependencies are as follows? > media-libs/libpng # Needed?

This is required if you want to use the GtkCairo backend. Pango is a dependency of cairo, but not a direct dependency of matplotlib. If your platform does package dependency resolution, that should be taken care of automatically. > excel? ( dev-python/xlwt ) See above. > latex?

Optionally, you'll want PyQt4 or PySide, wxPython, pygtk (pygobject on Python 3) or tkinter. But you only need one GUI framework of your preference. If using pygtk or tkinter, you'll also need to install the development headers. > > I started to follow the development of MPL a bit and IIRC it is > now possible to install a python3 version along with the Python2.

I remember, that > there were some issues, but do not know whether they were resolved. The issues is that you can't use Gtk with Agg, only with Cairo under Python 3. I've put a mailing list message into the pygobject developers about adding the necessary functionality to make this work, but have received no response for months. > > Maybe it would be a good idea to reflect the Python3 status/dependencies > in the documentation?
