[ncl-talk] Add text and polymarkers on panel plots

[Tabish Ansari]

Hi

I'm able to add text and polymarkers of separate plots but not able to
panel them properly. The text and polymarkers are being added on the
original plots and then a panel is being displayed on top of that without
the text and polymarkers.

Here's my code:
