I'm not sure that I totally understand what you are trying to do, but if you
would like to interactively annotate plots and graphics windows, then you
can use annotate.pro which is supplied with IDL. This is a simple drawing
program.
In addition, if annotate.pro is not exactly what you need, it demonstrates some
pretty powerful techniques for manipulating graphic objects and is worth
looking at anyway.
I hope this helps.
