#4 More gnuplot/gnugraph options

[Henry]

gwave lets you export plot data to postscript, png, or a variety of other formats using gnuplot or gnugraph. It would be nice to have a GUI that gives you more control over the output though, such as colors (background, individual waveforms), grid lines, etc.

I think this would just require adding some extra option control lines to the gnuplot/gnugraph scripts gwave already generates when it creates plots and would make gwave vastly more useful.
