[gradsusr] Plot wind time series

[MIGUEL FIDENCIO SAAVEDRA JUAN DE DIOS]

Hello all:
I want to get wind graphs as the attached figure (windvecSabine.png).


With the grads script that I attached, the results are not as expected
(vector.png) .
 Please someone have a suggestion?

$ cat vector-time.gs
'open total2015.ctl'
'set display color white'
'set lat -10'
'set lon -81'
'set t 1 10'
'set gxout vector'
*'set vpage -5 5 -8 8'
'd const(u,0);v;mag(u,v)'
*'d u;v;mag(u,v)'
*'d u-u;v;mag(u-u,v)'
'printim vector.png'
'!display vector.png'

my ctl is:
cat total2015.ctl
DSET ^2015%m2%d2.dat
OPTIONS TEMPLATE
