[gradsusr] Scatter plot

[Mary Ndlovu]

Hi. 

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 
 file 1: Xsize = 360  Ysize = 180  Zsize = 1  Tsize = 1715
file 2: Xsize = 720  Ysize = 360  Zsize = 1  Tsize = 1320

Now i have since converted these to a T42 Gaussian grid, which means i get for both 
Xsize = 128  Ysize = 64  Zsize = 1 

But now i get an error telling me that 
Error plotting scatter plot:  Invalid grids
   The two grids have difference scaling. I am out of ideas now.

              Mary:
    
    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.

 Hi, 
              
              Please help me. I am trying to plot a scatter plot from 2              different files. The 2 variables are sst; rf... so file 1              has sst, file 2 has rf. So when i do
              'd sst ; rf.2'
              i get an error message 
                      
          
 Data Request Error: Invalid grid coordinates
              World coordinates convert to non-integer grid coordinates
                Variable = rf.2  Dimension = 0 
              Error ocurred at column 1
            DISPLAY error:  Invalid expression 
              Expression = rf.2
            
            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
            
            I have converted the grid
