Re: Ngl.overlay and Ngl.panel

Hi Ivan,

The problem is that the Ngl,overlay function is not preserving
information about
the contour plot, so the Ngl.panel function doesn't know how to
retrieve contour
level information in order to generate the labelbar.

I think a quick fix will be to do this right after the second
Ngl.overlay call:

    map.contour = cfill.base

Let me know if this doesn't work. I'm assuming the "cfill" contour is
the
one that you want the labelbar information to be generated for.
