Unless I completely misunderstand what I am seeing, it
appears to work for *all* the text on the axis. Do you
have an example that doesn't work, Mark? I'm using
IDL 5.2.1.

Uh, I think you can turn this off under the Global
Options/Replying tab, Mark. But I always appreciate
learning about other innovative solutions. :-)
Cheers,

Thank you David.

Did you ever read the object graphics book that belonged
to the course?
I know that we had no time to open it during the course.
Now when I came home and tried to find things in there
I noticed that they used object programming only for the
graphic elements in the book.
Some vital parts of the object oriented stuff with
methods and windows was missing from the book.
Fortunately I still remember how to do it.

The Recompute_Dimensions=2 fixed it.
I am actually starting to like object graphics more
all the time. The thing that really makes a difference is
the professional feel of the user interface and the
modularity of the code.
Besides, programming in this style opens up new views
all the time. It is quite refreshing.

Whoops! This was something that I thought to mention
several times in the course last week and every time
promptly forgot to do it in the heat of battle. :-)
What we want to do here is recompute the text scaling
when we change the axis range that the text object
is attached to. We can control when the scaling occurs
by setting the RECOMPUTE_DIMENSIONS property of the
text object. In this case, you would like to *always*
recompute the text dimensions, so I would set this
property at the same time you assign the font object
to the text object in the INIT method of your object:
axistext->setproperty, font=self.complexPlotFont, $
Recompute_Dimensions=2
Cheers,
David
