I'm not sure I understand how to find where the XTITLE would have been
placed on the plot, in the monochrome case. If you knew where the XTITLE
would have been placed, then it seems that using XYOUTS would work great.
For example, the monochrome case would be
PLOT, findgen(20), xtitle = 'This is a cool title'
It seems to me you're saying that if I wanted the word 'cool' to be blue,
I could do the following:
1. PLOT, findgen(20)
2. Break the title string into 3 strings
3. Make 3 calls to XYOUTS
So my question is, how would I know the correct positions to send to
XYOUTS so that the xtitle appears in the same place as it would as if I
had just called
PLOT, findgen(20), xtitle='this is a cool title'
???
