As a friend of mine said, http://matplotlib.sourceforge.net/license.html
"This term is moderately odious:" 3. In the event Licensee prepares a derivative work that is based on or incorporates matplotlib 0.98.1 or any part thereof, and wants to make the derivative work available to others as provided herein, then Licensee hereby agrees to include in any such work a brief summary of the changes made to matplotlib 0.98.1. but in any case, Damien, thanks a lot, because you have made me discover exactly what I was looking for (or very close to, at least). Not only the license but in general matplotlib seems to match my requirements very well. I was really looking forward to getting something like supermongo/ gnuplot but more... user-friendly , more powerful and... with a nicer license. I see also by the way that you are the maintainer, so again thanks for porting it to OpenBSD!
