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.
