Re: Paneling attached plots

Hey Carl,

You make a great point about calls from within a function, but
unfortunately that's not how I'm calling things. If we're all good with
talking more pseudo-code, this is basically how my calls are being made.

I would think looping through an array of graphics objects wouldn't be any
different then creating them in a function and ensuring the function passes
the graphics ID back to the main portion of the script (e.g. what Carl
suggested), but someone correct me if that's wrong. I'll see if I can find
a similar non-looping solution that might work, too.

do k=0,2
  a(k) = gsn_csm_contour
  b(k) = gsn_csm_x2y
  c(k) = gsn_csm_x2y
  overlay(b(k),c(k))
  plot(k) = gsn_attach_plots(a(k),b(k))
end do
