Take a look at the matplotlib library: http://matplotlib.sourceforge.net/


Especially the gallery page - there are several examples of what you can do. It may not be the easiest thing to start into as a beginner, but it's definitely available.


If you're interested in doing a lot of scientific stuff, I'd also recommend using Python(X, Y): http://www.pythonxy.com/ as it bundles most of the tools you'll need (such as matplotlib) into one easy installer.


Give it a try and if you get stuck, send us another email with what you've done, what you expect it to do, and what it actually does instead (including the full text of any and all tracebacks).


HTH,
