Ah ha, this exactly what I wanted colorbar to do!! The reason I had
never been able to get it done is that was a lot of work (and work I
didn't know how to do), it seems like a flag to colorbar or tvlct or
something that was /logscl would do the trick. Really the issue was my
unfamiliarity with logscl, tvlct, and tvimage and how to put it all
together.
Cheers,
Brian
