Greetings to all from a new user of scipy! My environment for scipy consists of a PC running Windows 2000 with Cygwin (full installation, in the last month) & its Python2.3, and scipy and f2py2e installed from the CVS repositories. Here's my question: I'm using the scipy.gplt routines to visualize some 3d data sets, and getting pretty good plots on the Xwindows terminal, but I don't appear to be able to write plots to files. For example, the fragment ... plotting commands... gplt.output(filename, 'epslatex color') gplt.close() with filename "myfile.eps" does generate a file "myfile.eps" in my working directory, which I can open with Adobe PhotoShop, but there is no graph in it. I get similar results with a png file. The documentation refers to drivers needed gnuplot -- how can I tell whether I have any installed, and how can I obtain and install them if I need to? Thanks very much in advance for any help! George Christianson
