The Enthought Free Python Distribution (EPD Free), is a free Python distribution from Enthought, which includes additional Python packages / modules for scientific computing and graphing / plotting, such as SciPy, matplotlib and more.
I downloaded and installed it, and tried out some of the matplotlib examples in the Examples directory of the installation.
They worked fine.
Only tried it out a little so far, but I've known about Enthought for some time now, and it looks like a useful Python distribution for the stated purposes. They also have higher versions, presumably for pay, with support, etc.
