格点数据画图求助

墨青衫

有txt文本的格点，360*720*17的  0.5°*0.5°的数据

程序如下
begin
finame = "d:/222.txt"
nrow = numAsciiRow(finame)
data = asciiread(finame, (/nrow/), "integer")
data@_FillValue = -999
data2=onedtond(data,(/360,720,17/))
data2@_FillValue = -999
data2=data2/100
data2!0="lat"
data2!1="lon"
lat = fspan(-90,90,360)
lon = fspan(0,360,720)
lon@units = "degrees_east"
lat@units = "degrees_north"
data2&lat = lat
data2&lon = lon
wks = gsn_open_wks("ps", "d:/1")
gsn_define_colormap(wks,"WhBlGrYeRe") ; 设置色表
res = True
res@sfXArray=lon
res@sfYArray=lat
res@cnFillOn = True ; 填色
res@cnLinesOn = False ; 去掉等值线
res@cnLineLabelsOn = False ; 去掉等值线的数字
res@cnInfoLabelOn = False ; 去掉右下角说明
res@gsnSpreadColors = True ; 6.1.0 后默认即为 True
res@lbBoxLinesOn = False ; Label bar 上不标记黑线
res@gsnRightString = ""
res@gsnAddCyclic=False
plot = gsn_csm_contour_map(wks, data2(:,:,0), res)
end
求大神指导一下应该怎么做，是哪里出错了呢
