I once remember looking at some impressive plotting library for Python. Unfortunately, I don't remember the URL or the name of the package. So when I found the new library which has the same syntax as Matlab I said I couldn't miss this. So here we go with my reminder to myself to check it out after the exams!
Matplotlib at http://nitace.bsd.uchicago.edu:8080/matplotlib
If you know of any other plotting library that you really like do let me know!
