<p>Kalyan,</p>
<p>Does your display show "Entire Grid Undefined" or is it simply a
blank map? Using your descriptor file and data set if I do:</p>
ga-> open model<br>
ga-> d HGTprs(lev=500)-HGTprs(lev=<wbr>1000)<br>
<br>
I get a blank screen (image1.png). If instead I do this:<br>
<br>
ga-> open model<br>
ga-> set gxout grfill<br>
ga-> d HGTprs(lev=500)-HGTprs(lev=<wbr>1000)<br>
<br>
I see a bunch of scattered points (image2.png). Zooming to an
arbitrary 10x10-degree region you can see these in more detail
(image3.png)<br>
<br>
ga-> open model<br>
ga-> set gxout grfill<br>
ga-> set lat 20 30<br>
ga-> set lat 10 20<br>
ga-> set lon -160 -140<br>
ga-> d HGTprs(lev=500)-HGTprs(lev=<wbr>1000)<br>
<br>
I believe this means you don't have enough contiguous points to
generate contours, thus the need for gxout=grfill.<br>

<p>Hi Kalyan,</p>
<p>There are a lot of missing data in your file, so that
might be why contours/shading doesn't show up. If you
use "set gxout grfill" before "d thick" you can see all
the valid grid cells. Also note that your longitude
values are somewhat unconventional and run from -220
-0.4375 (140E to 0), so make sure your "set lon x1 x1"
is within that range.</p>
