You have been working on this for half a month, and it
never once occurred to you to use a COLOR keyword
on XYOUTS. Sigh... You must be a man of great
faith, my friend!

I would do a couple of things. First, I would give
your color bar a range that wasn't zero, so it would
actually appear on your display.

Then, I would byte scale the values you plan to
display in color.

Finally, I would use a COLOR keyword to indicate
which color you want to use when you write the
city name.

Cheers,

David
