[ncl-talk] add text problem in Draw Order

[Mary Haley]

Hi Erika,

Whenever you call gsn_text or gsn_text_ndc, the text is drawn at that
moment. This means if you draw anything later, it will likely be drawn on
top of the text.

You try calling gsn_text_ndc after you call gsn_attach_plots, but you may
need to adjust your string position and size.
