Axis annotation size is some percentage of CHARSIZE. They can be
set independently of CHARSIZE, using [XYZ]CHARSIZE keywords, but
if you change CHARSIZE, you will change the axis annotation size, too.

Use a bigger graphics window. ;-)
Just don't use CHARSIZE keywords or IDL (and you!) will be
*extremely* confused. The point is, when you use !P.MULTI you
give up this kind of control. If you don't like it, do your
own damn thing. This is what the NOERASE and POSITION keywords
are all about. :-)

The problem is, a 12-pt character size is undefined everywhere
except on a off-set printer using hot type. It's not much good
for a computer display. :-(
