Yes, when I type *this* command I see labels on both sides of the bar.
But, if I type the command correctly:
IDL> cgColorBar, range=[1,300], /Vertical, FORMAT='(F4.0)', /Window
It works correctly.
Cheers,
David

Humm. Can't check right this minute, but are you using the LATEST
colorbar routine:

It is important that your Coyote Library is up to date.

Ok, here are a few examples of what is going on.
The FORMAT works as expected with a horizontal color bar:
IDL> cgColorBar, range=[1,300], XTICKFORMAT='(F4.0)', /Window
And the vertical color bar without FORMAT also looks as you'd want:
IDL> cgColorBar, range=[1,300], /Vertical, /Window
But add the FORMAT to those Y values and suddenly the tick labels show up on both the right and left of the vertical color bar! (Regardless of using the /right keyword or not):
IDL> cgColorBar, range=[1,300], /Vertical, YTICKFORMAT='(F4.0)', /Window
What am I doing wrong?

Perhaps I've broken the expectation paradiem here, but the FORMAT
keyword should work. I've done this so I have one keyword that works
with either vertical or horizontal color bars. :-)

I thought that YTICKFORMAT should work, but it gives a funny display (labels on both sides of the color bar) so I had considered that it wasn't a compatible keyword with cgColorbar. I'm running 8.2 on a Mac. Does that keyword typically work?
And the cgControl, execute... worked wonderfully. Thank you!

But when it moves on to the second call, it erases what it just plotted and then re-draws the A data set before drawing the B data set on top of it. The end result is correct (2 curves overplotted), but the drawing of the A data set twice is undesirable. For large data intervals, the plotting time ends up being on the order of minutes and the time sink for re-plotting A is driving me nuts. Any idea what causes/fixes this?

Sometimes when I plot this the color bar labels look like so: [1, 10, 10^2, 10^3, 10^4....], where the carrot-raised number actually appears as an exponential. Other times (without changing the code whatsoever) the labels come out like this: [1, 10, 100, 1000, 10000....]. The parameter that determines the display format is the limit of the range - if it goes up to 10^5 or higher, everything stays in exponential format. If the maximum range is 10^4 or lower, it displays in regular format. Suggestions on how to force the exponential display?

To disable updating while you put several data sets on the plot,
temporarily turn updating of the cgwindow off:
cgcontrol, execute=0
...do all of your cgplots commands...
cgcontrol, execute=1

In order to be able to resize the plots in the window, the position of each plot has to be recalculated and then each plot has to be re-displayed to the correct size. So, A will be replotted after each re-size.
Anything with /addCMD probably falls into this re-plotting loop.

I should note that, for the cgPlotS problem, it does NOT draw A twice over in the normal IDL display (take out all the /Window and /AddCMDs). There, it plots A once and then B over top, as one would expect.
