NCL有三个添加文本的接口:gsn_text(图形坐标)、gsn_text_ndc(页面坐标)和gsn_add_text。只有最后一个函数会将文本和图形结合在一起。例: add_T = "text here" x = 0.5 ; middle of x y = 0.85 ; towards top of page txres = True txres@txFontHeightF = 0.03 gsn_text_ndc(wks,plot,add_T,...
Otherwise, you can setthe cnFillColors or vcLevelColors to arrays of color indices or names.Run the following script and compare the color fills in the two frames:title = This is a titleCwith a carriage returntxres = TruetxrestxFontHeightF = 0.03gsn_text_ndc(wks,title,0.5,0.5,txres)...

这样所有数据就保存到各个变量中啦！每个变量都是⼀个⼀维数组。⼆、将站点数据使⽤各种差值函数转换成格点数据。注意使⽤这些函数的时候要在⽂件头部包含contributed.ncl，即：load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
