<br>
I'm having trouble superimposing two graphs from different dat files.<br>
One file was custom made by a colleague which has temp from Feb 2 to<br>
Feb 7 among other variables. The second dat file comes right out of a<br>
WRF simulation, which was then sent through ARWpost for Feb 1 to Feb<br>
5. When I open the ctl files individually on Grads, I can plot the<br>
graphs of the respective data. But, when I open both ctl files in a<br>
single Grads session, only the first file will be able to plot<br>
anything. Right now, I'm only interested in plotting temperature in<br>
Celsius from Feb 2 to Feb 5 over a specific station. (Variable 'tc'<br>
from the ARWpost ctl, and variable 'temp' from my colleagues data.)<br>
Here's the error message:<br>
<br>
Data Request Error: Invalid grid coordinates<br>
World coordinates convert to non-integer grid coordinates<br>
Variable = tc.2 Dimension = 0<br>
Error ocurred at column 1<br>
DISPLAY error: Invalid expression<br>
Expression = tc.2<br>
<br>
Thoughts?<br>
<br>
Any help would be greatly appreciated!<br>
