I guess a definition of "work right" depends on what
you do with it. cgColorbar has "worked right" for me
for quite a few years. :-)
Getting a color bar to "work right" is probably why
IDL never provided one. This routine, probably more
than most, allows you to do pretty much everything
that needs to be done. In that sense, it probably
works OK, at the very least.
But, you may be right. I know I chose the default
format of "I0" specifically so that it would be "wrong"
in some instances so that people would have to go
looking for how to make it right. After I did that,
and people discovered that there was actually
documentation in the file(!), my support calls went
way down. :-)
Cheers,
David

I have a PC intel core i5, it's an usual desktop.
My only library installed in the machine is the Coyote!
I didn't know there was a better routine to draw color bars. I'll try
to use cgColorbar.
Thanks for the tip.
Vito

Well, I'm not convinced. What kind of a machine are you
running this on? :-)
Do you have any astronomy library installed? In particular,
do you have the SolarSoft library installed?
Is there a particular reason you want to use this
object color bar anyway? I'll be honest with you,
I think I've used it twice in my life. I just find
cgColorbar so much more convenient for nearly everything
I do that needs a color bar.
Cheers,
David

Hi David, thanks for answering.
Yes, the command printed out only my Coyote Library!
I have installed in my PC both IDL versions, 7.0 and 8.0. Could that
be a problem?
I checked my code and everything seems to be right, since it works in
version 7.0.
Another error message I got in IDL 8.0 is "Error in Draw Method.
Returning..." :-(
Vito.

OK, perhaps I should have said "work better" :-)
Did you try the example I gave w/ and w/o the changes?
