[ncl-talk] About mesh range of lon lat plot.

[Mary Haley]

Tao,

Please see attached script and image.  This shows what a raster plot is
doing.  NCL constructs a box around each data value, and whatever range of
your contour levels this data value falls in, the box will be filled in
that color.

The dots in the image show the X,Y locations of the data, which you can see
are centered in the box that NCL constructs.  The values show the actual
value of that data point.
