[ncl-talk] Map Coming Up Short

[Adam Phillips]

Hi Barry,
I am guessing that the data is being drawn to the boundary of the data
coordinates of your overlay plot. You will not be able to get NCL to draw
anything outside of the data coordinates. Thus, short of interpolating your
data to a different grid, I believe your only choice would be to try
different map projections and map limits. This will only truly be done via
trial-and-error. You will want to set mpProjection along with various
mpLimitMode related resources. (You are already setting
 mpMinLatF/mpMaxLatF/mpMinLonF/mpMaxLonF with mpLimitMode = "LatLon" (the
default)., and plotting on a cylindrical equidistant projection (again, the
default).)

The NCL examples website has numerous examples.
http://www.ncl.ucar.edu/Applications/, specifically see the Map Projections
examples. As you stated that your data is on a Lambert grid, you might want
to start with the Lambert Conformal examples.

Hope that helps. If not, please respond to the ncl-talk email list.
