I agree that this currently works best for a simple hard-coded
journal-article type plot, but I think that this is still even easier
than you think it is. I do believe this could be a full-featured
program that handles 95% of your average PLOT and SURFACE calls, with
far less work than Hercules, Atlas, or Samson ever did. But no, I will
not write it as I have no need for this, outside of a few simple
hard-coded journal-article type plots. :)

1) There is no limitation of 3. You can pass in an array of
substrings, and an optional associated array of colors you want them,
and break the title into n substrings. The only requirement here is
that each substring matches only one regexp. But most titles do not
repeat words, so this should work.

2) You can center XYOUTS perfectly via this method: Write once
offscreen ("XYOUTS, 10, 10, /norm, title, width=w") to get the length
of the entire string (or write twice on-screen, the 2nd time in the
background color to erase it). Knowing the length of the string, and
!position, and CONVERT_COORD will allow you to make an XYOUTS
indistinguishable from an "XTITLE=" keyword to plot

3) If you then use CONVERT_COORD to work in data coordinates, I think
you could even get colors working for words in a 3D PLOT or SURFACE,
where your axes are skewed, using /T3D with XYOUTS.

-k.
