grads中aave

饶红红

我根据这样算出了每年2月份各个各点的anomaly，我要怎样用aave把每年2月份的区域anomaly算出来并绘制成折线图？
'reinit'
'sdfopen D:\ElNino\HadISST_sst.nc'
'enable print D:\ElNino\nino2.gmf'
'set lon -170 -120'
'set lat -5 5'
'set lev 0'
iyear=1870
while(iyear<=1987)
'set t 1'
'define save22=ave(sst,time=11:59Z16FEB'iyear',time=11:59Z16FEB'iyear'+29,12mo)'
iyear=iyear+1
endwhile
'define save2=ave(save22,time=FEB1870,time=FEB1987,1yr)'
iyear=1870
while(iyear<=2017)
'set time 11:59Z16FEB'iyear''
'define nino2=sst-save2'
'd nino2'
'draw title 'iyear'nino2'
'print'
'c'
iyear=iyear+1
endwhile
'disable print'
