Gnuplot does have a driver for the UNIX plot command.  A the BSD version of this
command is available on Apollo.  If your TERM variable is one of the apollo types,
plot will create a DM pad and draw in it.

Here's an example of using gnuplot with plot:

    $ /usr/local/bin/gnuplot | plot
    
    	G N U P L O T
    	unix version 1.10A (Polar)
    	Copyright (C) 1986, 1987  Thomas Williams, Colin Kelley
    
    gnuplot> set terminal unixplot
    gnuplot> plot sin(x)
    gnuplot> q


Note that since the UNIX plot command does automatic scaling, it can't begin
plotting until it has seen the entire set of plotting commands it recieves
from standard input (in this case a pipe from gnuplot). Thus, unfortunately, the
DM pad won't get created and you won't see the graphics until you exit out of
gnuplot, meaning you can only draw one graph per gnuplot session.

If that solution is unacceptible to you, note that I have developed a GPR driver
for gnuplot, but I don't know what the procedure is to submit a driver to FSF
or whomever distributes gnuplot so that it becomes part of the gnuplot
distribution, if someone knows, please let me know.
