[gradsusr] Plotting for different time sets

[Mary Ndlovu]

Hi,

I am having a problem plotting 3 datasets into one plot (i.e using *aave *).
I  can do them individually and found out that i get an error '* World
coordinates convert to non-integer  grid coordinates'* when i try to plot
them on the same figure. So i figured out that I could change the grid, but
i still get the same problem, which i think is Time related....

Default file number is: 1
X is varying   Lon = 0 to 360   X = 1 to 321
Y is varying   Lat = -89.1415 to 89.1415   Y = 1 to 160
Z is fixed     Lev = 0  Z = 1
T is fixed     *Time = 00Z15SEP1957  T = 1*
E is fixed     Ens = 1  E = 1


X is varying   Lon = 0 to 360   X = 1 to 321
Y is varying   Lat = -89.1415 to 89.1415   Y = 1 to 160
Z is fixed     Lev = 0  Z = 1
T is fixed     *Time = 00Z15JAN1851*  T = 1
E is fixed     Ens = 1  E = 1

X is varying   Lon = 0 to 360   X = 1 to 321
Y is varying   Lat = -89.1415 to 89.1415   Y = 1 to 160
Z is fixed     Lev = 0  Z = 1
T is fixed     *Time = 00Z15JAN1901  T = 1*
E is fixed     Ens = 1  E = 1

So i tried to use the first file's  time in my expression
preca=aave(*pr.2(t=1)*, lon, lat..........)
... and it works.. Unfortunately i do not get a time series, i get a
constant. I am using GRADS Version 2.0.a9, and the files i use open with
'sdfopen' because i saw there was something like TDEF on some documentation
which unfortunately works with xdfopen. Please help me... What can i do to
have all these series in one plot.

Thank you very much
