Thanks for the reply.  

Apologies for the poor description. Let me try again.

The code produces 4 charts in a 2 by 2 matrix

Above these charts I have a single, left justified title in the outer
margin.

I would like to embed this title in a box which should run from the left
hand side of the screen to the right and be say 10 lines high. I would like
to color the box background red, the title "MY TITLE" would appear in blue
inside the box. This could be described as a header.   

Any better?
