OK, so here is what is happening.

Here are your colorbar coordinates:

;set colorbar coordinates
cposx1=0.2
cposy1=0.08
cposx2=0.6
cposy2=0.09

These are coordinates, obviously, of a HORIZONTAL color bar. That is,
the bar is much longer in X than in Y. But, you tell your color bar that
you want a VERTICAL colorbar.

This make absolutely no sense to the color bar program. So, it says to
itself, "This guy obviously doesn't know what he wants, so I'm thinking
he probably got the damn coordinates wrong." And the colorbar routine
switches things around so the you get the vertical color bar you are
suppose to get. But, the TITLE doesn't seem to be getting word of this,
so it goes on what it thinks is the original HORIZONTAL bar.

The COLORBAR routine you are using is so old I'm not exactly sure how it
works, to be honest with you. I haven't seen that code for about five
years. But, I think your problems will be solved if you simply match
your colorbar coordinates with the type of bar you are trying to draw.

Cheers,

David
