if you want to plot graphs :

use pydot the wrapper for graphviz
      http://dkbza.org/pydot.html
      http://www.research.att.com/sw/tools/graphviz/

if you want to plot datas (2d) :
matplotlib
      http://sourceforge.net/projects/matplotlib
or (2d/3d) dislin (=a plotting library with a python-wrapper)
      http://www.dislin.de/
