No one is more anal about these kinds of things than I am,
but this doesn't seem like a particularly big deal to me.
Do everything in normalized coordinates. You can find you
bearings with [!X, !Y].window. You can easily rotate your
title text with XYOUTS and center it with ALIGNMENT=0.5,
no need to fuss about string length at all. The AXIS
command will put an axis anywhere you like.
Cheers,
David
