Well, this is a fairly subtle problem, it seems to me
after I've puzzled over it for an hour. I think it
boils down to the fact that you don't want to simultaneously
use strings for your plot annotations AND use the FORMAT
keyword. I guess this makes sense. If you are asking IDL
to use strings you have provided, then the format will be
determined by the strings.
Bottom line, I think this call above will work if you set
the FORMAT keyword equal to a null string (ie, FORMAT='').
This will have to be done for COLORBAR *whenever* you provide
the [XY]TICKNAME keyword.
Cheers,
David
