Yes, /OVERPLOT was missing and I've added it to the example.
I guess the *point* of that example was no axes, but
perhaps I didn't stress it enough. With TVImage you can
have axes without saving the coordinate system (like the
TV command), axes with the coordinate system (by setting
both AXES and SAVE), or no axes and the coordinate
system (as in the example, with just SAVE).
The problem with TVImage (as it always seems to be!)
is too much baggage. Originally it started out to be
like TV. In retrospect that may have been the worst
mistake I ever made in my IDL career. :-)
In any case, I need more and better examples of what
you can do with these routines. But since this is
*exactly* what my new book is about, its a choice
between writing examples for my web page or for my
book. I'll bet you can guess which option has a better
chance of paying off. ;-)
Cheers,
David
P.S. By the way, I'm working on FSC_Plot tonight.
I've got a new SYMCOLOR keyword, so you can plot
symbols in a (different) single color from the
axes and from the data. Very slick. I'm still working
on making vectors of symbols and colors. By the way,
you can now use any of the 46 symbols available in
SymCat, including the paltry 8 or so that you could get
with the PLOT command. :-)
