Hello,
I don't use Windows, so I won't be of much help. Therefore, I am
forwarding your question to the gnuplot-users mailing list, where
several windows users are subscribed and might have ideas.
It sounds vaguely like the gnuplot program was never started. One thing
appears incorrect in your attempt:
> I also tried to type:
> Gnuplot.GnuplotOpts.gnuplot_command = "C:\Programmi\gp373w32\pgnuplot"
Because of Python's treatment of backslashes in strings, I think you
want to type either
Gnuplot.GnuplotOpts.gnuplot_command = "C:\\Programmi\\gp373w32\\pgnuplot"
or
Gnuplot.GnuplotOpts.gnuplot_command = r"C:\Programmi\gp373w32\pgnuplot"
Maybe that will help.
