Re: ASCII data plot

Hello All

I would like to read grid file of two variables (taox, taoy) in order to 
plot a vector field. But somehow when I list the values they are not 
consistent with my field.

file/var=alon lon1.dat
file/var=alat lat1.dat

define axis/from_data/x/name=mlon/units=deg alon[d=1]
define axis/from_data/y/name=mlat/units=deg alat[d=2]
define axis/t=1:1:1 mtime
define grid/x=mlon/y=mlat/t=mtime mygrid

cancel data/all
file/var="taox,taoy"/Columns=6/grid=mygrid var.dat
save/clobber/file=var.cdf taox, taoy


Here is the data set
1 2 3.5 6 2 1
2 7.1 9 3 2 2
4 0 1 9 2 1
1.5 2.5 3 3 6 9

1 2 3.5 6 2 1
2 7.1 9 3 2 2
4 0 1 9 2 1
1.5 2.5 3 3 6 9

Here is my erroneous listing

yes? list taox
             VARIABLE : TAOX
             FILENAME : var.dat
             SUBSET   : 6 by 4 points (LONGITUDE-LATITUDE)
             T        : 1
              90W    89.5W  89W    88.5W  88W    87.5W
                1      2      3      4      5      6
 19.5N  / 4:  4.000  1.000  2.000  1.500  3.000  6.000
 19N    / 3:  1.000  3.500  2.000  2.000  9.000  2.000
 18.5N  / 2:  4.000  1.000  2.000  1.500  3.000  6.000
 18N    / 1:  1.000  3.500  2.000  2.000  9.000  2.000

yes? list taoy
             VARIABLE : TAOY
             FILENAME : var.dat
             SUBSET   : 6 by 4 points (LONGITUDE-LATITUDE)
             T        : 1
              90W    89.5W  89W    88.5W  88W    87.5W
                1      2      3      4      5      6
 19.5N  / 4:  0.000  9.000  1.000  2.500  3.000  9.000
 19N    / 3:  2.000  6.000  1.000  7.100  3.000  2.000
 18.5N  / 2:  0.000  9.000  1.000  2.500  3.000  9.000
 18N    / 1:  2.000  6.000  1.000  7.100  3.000  2.000


The grid points are consistent but the data are not. I cant figure out
the source of error.

Thanks in advance
