OK, but we are communicating with gnuplot through a one-directional
pipe. Do you have a reliable way to do two-way communication with
gnuplot?

Oh, I thought octave was using a two-way pipe, as it was pointed out
some time ago to get feedback from a click on the plot window.
If it's not the case, then I don't know...

Timothée, John,
With the gnuplot-4.2.rc2 installed on my G5 Mac, I get the following from
Timothée's suggested commands:
Joe-Koskis-Computer:~/Codes/EMD Revised Convergence jakoski$ gnuplot
<...>
Terminal type set to 'aqua'
gnuplot> set font "helvetica,24"
gnuplot> show variables all
<...>
Note that my change of font and font size does not show in the output. How
would the "read-only" variables such as GPVAL_X_MAX be accessed from the
interface? Is there a one-to-one mapping from all gnuplot set commands to
the "read-only" variables?
