Searching through past mailing lists and google and such it appears that it may be hard to find a "port" of Michael Haggerty's Gnuplot module that runs with numarray instead of Numeric. If I am incorrect about this I apologize for the wasted bandwidth. In the true open source tradition I have taken 5 minutes and replaced a bunch of instances of "Numeric" with "numarray" in the tar distribution that I got from http://prdownloads.sourceforge.net/gnuplot-py/gnuplot-py-1.7.tar.gz? download I then tested it for another 5 minutes on the project I was doing and then tarred it back up in case anyone else wants to have a go with it. The demo in the distribution runs and it works on the project that I am doing, but I haven't tested it any further. I have posted it at http://www.scipy.org/Members/spence/gnuplot-py-1.7-numarrayOSX.tar.gz/ file_view Let me know what you think. Best, Spence
