Hi,
I'm glad to hear you figured out how to do your variance
calculation. Did you use a nice simple _expression_ like var[t=@var]?
For example,
yes? use monthly_navy_winds
yes? let var_uwnd = uwnd[t=1-jan-1985:1-jan-1990@var]
yes? shade var_uwnd [x=150:300,y=0:30]
will be the variance over the given time range at each location on
the XY grid.
The error message is telling you that the variable nm1 is not a
single number, but a variable on a grid or axis with an extent
that's more than one coordinate.

Hallo,
I could figure it out. But i just wonder, why I couldn't used
this command:
and produce this error:
yes? go var_n
CANCEL MODE VERIFY
**ERROR: invalid command: grave accent doesnt evaluate to
scalar
nm1 eq 0
IF `nm1 eq 0` then exit/script
Command file, command group, or REPEAT execution aborted
Thanks for your help.

Hallo
Ferret Users,
Anybody has an experience to calculate the variance for
each grid during "ntime"
and then plot the results in 2D Map [LatxLon] for one
variable let say sst [ time x nlat x nlot].
Thanks for your kind help
