And you have to be careful when you convert to another graphics
device. All your carefully laid plans will go *poof*, when the size
of the canvas changes.
If you dispense with using plotting symbols altogether, couldn't you
draw your hexagons yourself? Using PLOTS, you certainly have the
maximum flexibility.
