I don't know because I haven't managed to get it working either. But
other people have and I guess it should not be so difficult.
I personally use gnuplot-py (gnuplot-py.sourceforge.net) which I adapted
to the new NumPy/SciPy (see below) by searching-and-replacing "Numeric"
by "numpy". It allows to use raw gnuplot commands.

There is the excellent SciPy package, which you can get at www.scipy.org
Personnally I use it a lot for linear algebra (linked to
LAPACK/ATLAS/BLAS), but there are also libraries for statistics,
optimization, signal processing, etc.
There has been many changes recently, including package names, so don't
get confused and be sure to get recent versions of NumPy and SciPy ;).
