This usually comes up when you have a point with an usually large
number, e.g., a land value incorrectly set. If you use "set gxout
grfill" you might find which point (or points) are incorrect. I
tried to open this file via opendap, and it works ok:<br>

I have Levitus 94 potential temperature monthly data file which<br>
is in ".cdf" format. I got it from the following link.<br>

I am using Grid Analysis and Display System (GrADS) Version
2.0.a6.<br>
<br>
I can make the contour plot, by using the command "set gxout
contour".<br>

ga-> sdfopen data.cdf<br>
Scanning self-describing file: data.cdf<br>
SDF file data.cdf is open as file 1<br>

theta 19 t,z,y,x potential temperature<br>
ga-> set gxout contour<br>
ga-> d theta<br>
Contouring: -3 to 30 interval 3 <br>
-------------------------------------------------------------------------------------------------<br>
<br>
But while I try to make the shaded plot, using the command "set
gxout shaded",<br>
I am getting the following error message. Please tell me<br>
how to solve this problem.<br>
