To smooth the curve

[Christophe LAVAYSSE]

Hello,

I have a 1D graph (gxout line) and I want to smooth this line (in y axis)
with GrADS.
If "time" is the variable I can use the tloop function
("tloop(ave(var,t-1,t+1))").

How can I do if the variable is z or y ? (tloop(ave(var,z-1,z+1)) is not
correct).

Thanks
