Well, that shouldn't prove too hard... all you have to do is to
write a small function that takes in a float and outputs a string
in the format you like. Granted, it may take a little while to do,
but I am sure it will be much faster than learning obj graphics.
And, you can use that function later on for labeling axis tick
marks as well, if you like.

Power Graphics with IDL by Ronn Kling would probably do you
more good for object graphics. :-)
And although it is VERY long in the tooth, and badly
needs updating, XCONTOUR still goes a long way in getting
you started along this path:

Thanks for both your answers.
I also thought about using c_annotate, but had hoped there'd be
another way.
Unfortunately, I don't know much about object graphics... So I should
probably get "IDL Programming Techniques, 2nd Edition", right?
Cheers, Michael

Yes, you might have to move to object graphics. Lots
of formatting available there. :-)

c_annotation perhaps?
Unfortunately you'll have to specifiy the levels explicitly.
e.g. contour, z, levels=[500000],c_annotation=["500,000"]
