If you open one file, and do a "q dims", you should see all the
dimensions. Do you get the<br>
exact same thing for both files (range and resolution, including for
time)? If not, you may <br>
have to interpolate one to the other.<br>

These are both .nc files. I think it has got to do something
with the grids (thanks for the heads up)... I figured out that
the original grids were
<div> file 1: Xsize = 360 Ysize = 180 Zsize = 1 Tsize =
1715<br>
file 2: Xsize = 720 Ysize = 360 Zsize = 1 Tsize = 1320<br>
<br>
Now i have since converted these to a T42 Gaussian grid,
which means i get for both <br>
Xsize = 128 Ysize = 64 Zsize = 1 <br>
<br>
But now i get an error telling me that <br>
<i>Error plotting scatter plot: Invalid grids<br>
The two grids have difference scaling</i>. I am out of
ideas now.<br>

This is likely because the two variables are on different
grids. The file with SST is loaded first, and the RF file
probably has a different definition for x/y/z/t. If you
can't sort it out try send the associated ctl files.<br>

Please help me. I am trying to plot a scatter

sst; rf... so file 1 has sst, file 2 has rf. So
when i do<br>
'd sst ; rf.2'<br>
i get an error message <br>

I have tried to convert the file to be grads
friendly... when i deal with this file on its own,
everything works fine... but in the scatter plot
it doesn't seem to work<br>

I have converted the grid <br>
