There's no need - I used Coyote Graphics (and your book) to do it first so I knew what was possible and what it could
look like. That, quite literally, took about an hour... and most of that time was spent re-reading your chapters on
image display, colours, colorbars etc. Writing the code was trivial.

Then, because I'm a stubborn masochistic procrastinator, I duplicated the effort in the new function graphics. THAT took
about 4 days (and it would've taken much much longer if not for your article on function graphics colourbar display on
your webpage).

And I'm still struggling with the $^@&#* colourbar in function graphics. When I display it horizontally, everything is
great. When I display it vertically, the function suddenly decides to ignore my TICKNAME labels and just use the byte
values of the image.... except for the first tick - that one is labelled correctly. Argh!

Anyhoo...

cheers,
