[ncl-talk] gsn_add_txt in panel plot

[Debasish Hazra]

Thanks Adam for the reply. Actually I want the circles and text shown in
the first figure only, not in the rest 11 ones. So, I do not need to create
any dummy variables for other figures. But the figure it generates only has
the marker circles but no texts in the first figure.
