Yes, it is all pretty baffling to begin with.  Nothing works quite the way you
expect it, and you have to work around various issues.

If you read the m-file for figure, you'll see it really only works for graphic
display terminals, i.e., X11 and aqua.  You need something different for
plotting to postscript.

Here is what I have found works for an eps file.
===========
gset term push;
gset term postscript eps color;
gset output "/dev/null";

[various commands to create the first plot]

gset output "plot1.eps";
replot;
pause (1); # this often seems required to get all output properly captured
gset output "/dev/null";
clg;

[various commands to create the second plot]

gset output "plot2.eps";
replot;
pause(1);

gset term pop;
gset output;

============

I recommend epstool for adding "tiff 6 packbits" previews to the eps files.

If xfig is available, you might find it convenient to use the fig terminal, and
then use fig2dev to convert it to eps format.  This allows editing the figure
using xfig and then recreating the eps file.  fig2dev is part of the transfig
package on debian and cygwin.
