Yeah, sure thing. Download it here:

My Perl wrapper is called "plotter". You'll see it. You'll also see the
directory which is the output of my PDE solver. It's called "data.22" (I
ran my PDE solver many many hundreds of times to cover a parameter space in
order to study the behavior of the PDE, so I resorted to uninspired names
for my data directory).
To see what options are available for my plotter, type:
./plotter --help
./plotter -h
./plotter -?
To see the plotter in action, try this:
./plotter -d data.22/ -x 1e-14 -y 4e14
The -x option sets the horizontal axis.
The -y option sets the vertical axis.
The -d option sets which directory to take the plot data from.
The -d option sets which directory to take the plot data from.
If the plot goes too fast, you can slow it down with the -p (pause) option,
which takes an integer argument:
./plotter -d data.22/ -x 1e-14 -y 4e14 -p1
The -x and -y options can have the form of:
-x from,to -x 2,100(x axis goes from 2 to 100)
-x ,to -x ,200 (x axis goes from 0 to 200)
-x from,-x 10, (x axis goes from 10 to last datapoint)
-x from -x 5(x axis goes from 5 to last datapoint)
It's loaded with options. You can change the point size and even convert
your graphs to eps files, suitable for including into your latex
dissertation. ;-)
Hope you find it useful. It was a lot of fun to write.

I had the same problem. My fix was to write a small perl script to wrap
around gnuplot.
The script writes a small gnuplot script and then invokes gnuplot with the
script.
When it comes time for a new plot, the script rewrites the gnuplot script,
kills all instances of gnuplot, and re-runs gnuplot with the new gnuplot
script.
It works surprisingly well.
Pete
PS- The data is output of a time evolution partial differential equation.
It creates a "movie" of the time evolution of a quantum wavefunction. Very
cool.
Are either of you familiar with octave (www.octave.org)? It is
essentially a high level numerical programming language. It uses
gnuplot as it's primary plotting interface and, by default, plots
everything in the same window. You could probably write your scripts in
octave if you were interested in doing so.

this produces a nice little graph updated once a minute. however, gnuplot on
linux produces a new window with every plot. on OSX it is possible to keep
all output in a single window* .
