I was going to tell you to look at 'multiplot' in gnuplot:
The command `set multiplot` places `gnuplot` in the multiplot mode, in which
several plots are placed on the same page, window, or screen.
...
But after seeing John's example, I honestly doubt it's worth the hassle with
Gnuplot. It would take a ridiculous amount of work with gnuplot to make that
kind of plot (and I've been using gnuplot since 1991!).
Time for me to finally check out matplotlib...
Best,
