The COLORBAR program, for historical reasons, as well as for
ease of programming, uses a PLOT command to do the annotation.
So, what you want to do is not possible with that code.
And because of recent changes, I can't even offer an undocumented
keyword solution that will completely scrub the bar of annotations,
so you could write your own axis labeling routine. :-(
I'd recommend just writing your own colorbar routine. You can use
PLOTS to draw your boxes on the colorbar image, and you can annotate it
however you like with XYOUTS.
Cheers,
David
