Here is a little function "exportplot" that I use for exporting plots.

I would recommend to export to fig-format and postprocess the output
with xfig. This offers more options than sticking to plain gnuplot's
capabilities.

Hope this helps,

  eval(sprintf("gset output \"%s\";", filename));
  eval(sprintf("gset term %s;", gplotterm));
  replot;

  ## reset default plotting values
  gset term x11;
  gset output;

endfunction
