Hi Mateus,

do you mean you want to set the upper limit of the y axis on your graph
to the maximum value in your data array?
In that case, let's say x is the vector with the data for the period you
are interested in. Define

datamax = max(x)

this gives you the maximum value of x. Then you can use the resources
trYMinF and trYMaxF to set the limits of your y axis. For example:

res = True
res@trYMinF = 0.
res@trYMaxF = datamax
plot = gsn_csm_xy(wks,x&time,x,res)

You can also look at example xy_5.ncl on the NCL website
