gr-sp
will display a set of postage-stamp spectra on the page. You provide a number of parameters defining the plot.
Second, use
cont
to obtain a contour plot.
Or, better yet (provided you are working on a Sun workstation or something similar), type
gray
to obtain a gray-scale plot. This can be turned into various colour schemes, with a number of options. I suggest you experiment; using the interactive mode is a good way to do this - type `h' within the plot to see the options available - or in non-interactive mode use the command
set-gray
Finally, either using s-p-d h and sending one of the above
commands, or typing see-map, will save the image to a file
(e.g. specx_pgplot.ps) suitable for output to the printer.
