I have now updated all the graphics routines in the Coyote
Library to take advantage of this method of specifying
Greek characters and other symbols.
Update your SVN code repository, or download the latest
version of the library from the code repository page:
http://idl-coyote.googlecode.com/
Or, from here:

Cheers,
David

Excellent David. Now how about subscripts and superscripts? Or is that already taken care of?
