I forget what error I got when I tried the same (I don't think it was the same as yours), but replacing the gdchart.pyd file with the Python 2.1 version available at http://athani.pair.com/msteed/software/gdchart/download.html seems to have done the trick for me. That site only has win32 binaries; you'll have to recompile if you're on another platform. Cheers, Jean
