Ansley,
Thanks for your response.
| I was able to download your file after all. I think that the only

| lont:modulo = " " ;

| lont:modulo = 360 ;
That's news to me! And I don't think that's right. Consider the
domain of a numerical model that extends from lon=0 to lon=180.
When modulo = 360, I expect that the model field is missing
for 180 <= lon <= 360, 540 <= lon <= 720, and so on.
But, when modulo = 180, I expect that the model field is defined
for any lon.
I think this is the PURPOSE of the modulo attribute, that is,
to allow for an arbitrary cyclic-domain size. In addition, Ferret
itself agrees with me! that is, it does exactly what I have
described. I have an netCDF file in which
float lonv(lonv) ;
lonv:units = "degrees_east" ;
lonv:axis = "X" ;
lonv:missing_value = -9.99e+33f ;
lonv:modulo = 100. ;
And Ferret does plot the field for whatever domain:
fill/k=1/l=1/x=-180:180 u
without any gap.
| Ferret will not draw a shade plot of data on a 1-point by n-point
| region
Hmm, I can see that FILL cannot work if the domain isn't cyclic.
But, I guess that SHADE can work whether the domain is cyclic or
not because it just paints gridcells without interpolation.
