[ncl-talk] gsn_add_txt in panel plot

Tue Nov 30 18:49:33 MST 2021

Thanks Adam. I added
dum2=gsn_add_text(wks,plot_A(0),"Test",lond(0)+1,latd(0)+1,False)  and it
worked. "Test" appeared on the first figure. I am wondering what is going
on, why dum2=gsn_add_text(wks,plot_A(0),strs(0),-28,23,txres)   one did not
work at first place ?
