I'm plotting seasonal average SST. Here I have picked traditional seasons as DJF, MAM, JJA, SON.
!seasonal average
use coads_climatology
let temp = SST[x=100,y=0]
let monthav = temp[l=@sbx:3]
let season = monthav[l=1:10:3]
!4 seasons DJF, MAM, JJA, SON
plot/col=0 temp
plot/step/ov season
go bar_chart3 poly/over season season
But here I'm missing values over December.I would like to define a time axis starting with December (Not with January). I tried regridding in time axis, But I couldn't get it.
