I am trying to help a student get started with
Python/Scipy/Numpy/Matplotlib in windows. On one of his machines,
everything seems to install correctly, we can call figure(1) without a
problem, and plotting is fine until we try the show() command. Then

I would need to create a timeline for a Latex document (eps output).
There may be other tools besides Matplotlib and I am open to

something along these lines:

It is probably overkill, but I use Latex for this. You can fairly

You can set matplotlib up to use LaTeX, but it can be a little bit of
work to get it going. The results are quite beautiful though.
set usetex = 1 in yout matplotlibrc file to try it out. It depends on
