Total annual precipitation

[bhatt vihang]

dear ben

why not to use reference card available on grads web
site. it is merely three pages has enough information
regarding frequently used commands.

the solution to your problem is

d ave(parameter,t=tmin,t=tmax)

where parameter is the variable you wish to plot
tmin is starting time index
tmax is ending time index

regards,
