That's a pity... I would have really liked to have a neat way to write
\dot{\rho} in a title! I'll just stick with the off centre point.
*sigh*

I use direct graphics (like plot, x, y) for you it may be different:
plot, x, xtitle='!sm!r!20!A7!n!x', charsize=4
In this example,
!s saves the current position
m draws the m character
!r restores the position (moving back to the start of m)
!20 changes the font to special math
!A moves up
7 draws the dot
!n moves back down to the normal level (and normal size)
!X changes back to whatever font you were before
For fuller details see the help section on "Embedded Font Selection
Commands" and "Positioning Commands" in the online help, or page 4434 in
the pdf reference manual (v6.1). "Formatting Command Examples" is pretty
useful.
The unfortunate side of this is that the dot is not centred. I don't
know how to do that - sorry!
The other alternative, if you speak tex/latex is to use tex2idl and tex
commands, found at:
