有没有大佬帮忙看一下,照着官网例子画的,为什么等值线会这么乱呢
数据处理
t=f->time
date=cd_calendar(t,-3)
z=short2flt(f->z(1,1,:,:))
u=short2flt(f->u(1,1,:,:))
v=short2flt(f->v(1,1,:,:))
c=short2flt(f->t(1,1,:,:))
h=z/98
copy_VarMeta(z,h)
h@units="dagdm"
T=c-273.15
Ts=smth9(smth9(smth9(T,0.50,0.25,True),0.5,0.25,True),0.5,0.25,True)
Tsm=smth9(smth9(smth9(Ts,0.50,0.25,True),0.5,0.25,True),0.5,0.25,True)
Tsmt=smth9(smth9(smth9(Tsm,0.50,0.25,True),0.5,0.25,True),0.5,0.25,True)
Tsmth=smth9(smth9(smth9(Tsmt,0.50,0.25,True),0.5,0.25,True),0.5,0.25,True)
copy_VarMeta(c,Tsmth)
Tsmth@units="~S~o~N~C"
等值线
levels =ispan(1000,1300,4)
h_res =res
h_res@cnLineColor ="NavyBlue"
h_res@cnLevelSelectionMode ="ExplicitLevels"
h_res@cnLevels = levels
h_res@cnLineLabelBackgroundColor = -1 ; transparent
h_res@cnLineThicknessF = 2.5
h_res@cnHighLabelsOn = True
h_res@cnLowLabelsOn = True
h_res@cnHighLabelBackgroundColor = -1
h_res@cnLowLabelBackgroundColor = -1
h_res@cnInfoLabelFontColor = "NavyBlue"
h_res@cnInfoLabelPerimOn = False
