If you don't mind using __gnuplot_set__, there is a relatively simple way to
plot without X. Try something like this:

=========
__gnuplot_set__ term push;
__gnuplot_set__ term postscript eps color;
__gnuplot_set__ output "/dev/null";

[commands to make your plot, exclusive of printing]

__gnuplot_set_output "output_file.eps";
replot;
pause(1);
__gnuplot_set__ term pop;
__gnuplot_set__ output;

========
The pause seems to be required at times to prevent garbling the output file.

This approach is very similar to what the print command actually does, if you
study the code.  It will not work if multiplot mode is invoked in the set of
plot commands (neither does print).
