[ncl-talk] margin top of viewport?

[Rick Brownrigg]

Hi,

I have to wonder if you might have better luck trying your annotations in
NDC space. There are a number of functions named "gsn_XXX_ndc() that
operate in this coordinate system. The function "drawNDCGrid()" can be
helpful in understanding what's going on.
