hi
if i have a global data T(lat ,lon) and T&lon is between -180~180
now i want to plot contour map in the domain 150E ~20W 20S~20N
so i set the
res@mpCenterLonF = 180
res@mpMaxLonF = 200
res@mpMinLonF = 150
res@mpMaxLatF = 20
res@mpMinLatF = -20
the question is if i writed the code like
plot = gsn_csm_contour_map(wks, T(ĄG,ĄG), res)
the label bar's value will show the global domain
but i just need the value in the range 150E ~20W 20S~20N
so i change the code to
plot = gsn_csm_contour_map(wks, T({-20ĄG20},{?ĄG?}), res)
if {?ĄG?} set to {150ĄG200) will got the error message bescause T&lon is between -180~180
how can i convert the coordinate variable to fit it or any suggestion to change the label bar value ?
Thank you
