Well, you certainly do not need the pre-2.0 release of octave to have multiple
plots. All you need is the beta of 3.6 release of gnuplot. Your gnuplot
version should be able to have multiple plots. I have the same release and
I can get multiple plots with your example. Make sure that the figure command
that you have is ok. All that needs to be issued by the figure command
is a command:

set term x11 <index>

where <index> is the number of display window.


Here's my version of figure command; check if that works:


------------------------- cut here ------------------------------------
function figure (index)

# usage: figure (index)
#
# Chooses a particular X-Window display for the next figure. This
# allows for use of the the gnuplot's X11 terminal object's ability to
# display multiple plot windows.
#
# Window indices start from 0.
#
# See other plotting commands also.

  if (nargin != 1)
    usage ("figure (index)");
  endif

  eval (['set term x11  ' num2str(index) ]);

endfunction
------------------------- cut here ---------------------------------------


P.S. By the way, I am still using the 1.1.1 version of octave.
