You could also consider google charts   Not technically a python API  but you can use it from python  it s reasonably fast to code for  and the results tend to look nice   If you happen to be using your plots online  then this would be an even better solution

I m the one supporting CairoPlot and I m very proud it came up here  Surely matplotlib is great  but I believe CairoPlot is better looking  So  for presentations and websites  it s a very good choice   Today I released version 1 1  If interested  check it out at CairoPlot v1 1  EDIT  After a long and cold winter  CairoPlot is being developed again  Check out the new version on GitHub

PLplot is a cross-platform software package for creating scientific plots  They aren t very pretty  eye catching   but they look good enough  Have a look at some examples  both source code and pictures    The PLplot core library can be used to create standard x-y plots  semi-log plots  log-log plots  contour plots  3D surface plots  mesh plots  bar charts and pie charts  It runs on Windows  2000  XP and Vista   Linux  Mac OS X  and other Unices

If you like to use gnuplot for plotting  you should consider Gnuplot py   It provides an object-oriented interface to gnuplot  and also allows you to pass commands directly to gnuplot   Unfortunately  it is no longer being actively developed

For interactive work  Matplotlib is the mature standard  It provides an OO-style API as well as a Matlab-style interactive API    Chaco is a more modern plotting library from the folks at Enthought  It uses Enthought s Kiva vector drawing library and currently works only with Wx and Qt with OpenGL on the way  Matplotlib has backends for Tk  Qt  Wx  Cocoa  and many image types such as PDF  EPS  PNG  etc    The main advantages of Chaco are its speed relative to Matplotlib and its integration with Enthought s Traits API for interactive applications
