Re: possible problem in panel_23.ncl example ...

Hi Ufuk,

Once you use gsn_csm_contour_map, it returns a map object, and not a
contour object. You need to pass the contour object to the labelbar
code
by changing the "contour(0)" argument to "contour@contour".

It looks a little awkward having the map object called "contour", so
you could do this:

   map = new(nplots,graphic) ; Array to hold plots
. . .
; Create and draw contour plot
     map(i) = gsn_csm_contour(wks,data(i,:,:),res)

   end do

; Create and draw a labelbar and main title.
   lb = labelbar(wks,map@contour)
