While this suggestion could be followed, it was a little
awkward, since NUMBER_FORMATTER was not set up to accept
arrays of numbers. Plus, this discussion pointed out a
couple of unanticipated weaknesses in the program. All
of these deficiencies have been addressed this morning.
You can find a new version in the usual place. :-)
Cheers,
David

This all has to do with the "natural length" of a number
and how these numbers are converted to strings. It can be
a mess. :-)
My guess is that one of your numbers changed from an
integer to a float, and it is that number you are using
in your strings.
My suggestion would be to use a program like NUMBER_FORMATTER,
which takes some of the mystery out of what you are going
to end up with. Or, alternatively, you can convert your numbers to
strings with the STRING function and the proper FORMAT
keyword. (Good luck!)

All of a sudden I am getting labels with 4 digits after the decimal.
So now they are overlapping one another. Before I didn't have any.
Does anyone know why this would happen? It worked fine after I put in
the STRTRIM function and then I was working on something else (my
function that created the particular color table for this routine). I
know this is vague but am I missing any intricacy of IDL or did I
accidentally change something?
ticks = StrTrim((SINDGEN((clrTableLength/5)+1)*5)-(clrTableLength/2) ,
2) <- David's line of code
ticks = STRTRIM((SINDGEN((clrTableLength/5)+1)*5)-(clrTableLength/2) ,
2) <- My line of code
Thanks,
Ryan.

Your strings are longer than you think they are. :-)
Try this command instead:
ticks = StrTrim((SINDGEN((clrTableLength/5)+1)*5)-(clrTableLength/2) ,2)

Shouldn't "divisions" = (clrTableLength/5)+1 ?
