[Matplotlib-users] exception error for matplotlib.use("WXAgg")

[jenya56 <je...@ya...>]

I get this error:
"Matplotlib backend_wx and backened_wxagg require wxPython>=2.8"
I have Python 26 and the most current versions of Matplotlib, basemap, and
numpy. 
Anybody? Thanks
PS On educational note: what do you really need backend for? thanks

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:
