Hello,

I have a huge dataset with random points of lon, lat and temperature
values (500,000).
I need to draw these on a map with the temperature being color-coded. I
know how
to create colormap and draw the points one by one using gsn_polymarker.
I would like
to know if there's any other way to draw the color-coded points using
NCL which will
speed up this process.

Thanks for any info
Yee
