Creating Titles on Multiple Plot Pages

QUESTION: I am using !P.MULTI to set up six plots on my page in a two-column by three-row arrangement. I want to put a title on this page, but I can't figure out how to leave room for it. How can I do it?

ANSWER: The outside margins of a multiple-plot page are controlled by the ![XYZ].OMARGIN system variables. These system variables use that ol' favorite of mine, character units, as the unit of measure.

Try something like this:

   !Y.OMARGIN=[2, 10]
   !P.MULTI = [0, 2, 3]
   FOR j = 0, 5 DO PLOT, FINDGEN(11)
   XYOUTS, 0.5, 0.93, ALIGN=0.5, CHARSIZE=2.0, /NORMAL, $
      'This is the plot title'

The code above produces this graphic.
