Do you have wxpython installed?

The matplotlib backends are what display windows with plots on your 
screen or know how to write various file formats.  In order to display a 
plot window, you will need to install the Python bindings for at least 
one of the supported GUI frameworks, (Gtk+, Qt, Tk, wxPython, or Fltk) 
and tell matplotlib which one to use.  See here:
