为什么我出的这个水汽通量散度图周围空出一片白色，脚本如下：'reinit''set grads off'
'set grid off'
'sdfopen e:\adqv\q.nc'
'sdfopen e:\adqv\u.nc'
'sdfopen e:\adqv\v.nc'
'enable print e:\adqv\adqv1.gmf'
'set lat 25 45'
'set lon 100 130'
'set vpage 0 11 0 8.5'
'set parea 0.8 10.8 1 8.3'
'set xlopts 1 4 0.20'
'set ylopts 1 4 0.20'
'set z 1'
'set t 6'
'set gxout shaded'
'set rgb 17 60 60 60'
'set rgb 18 120 120 120'
'set rgb 19 180 180 180'
'set rgb 20 220 220 220'
'set clevs -24 -12 0'
'set ccols 17 18 19 20'
'set grads off'
'define xflux=q*u.2'
'define yflux=q*v.3'
'define sqdiv=hdivg(xflux,yflux)*1e8'
'd sqdiv'
'cbarn 1.0 0'
'set gxout contour'
'set cthick 6'
'set ccolor 1'
'set cint 12'
'set grads off'
'd sqdiv'
'set grads off'
'q w2xy 110 28'
x1=subwrd(result,3)
y1=subwrd(result,6)
'q w2xy 122 34'
x2=subwrd(result,3)
y2=subwrd(result,6)
'draw rec 'x1' 'y1' 'x2' 'y2''
'print'
'disable print'
'reinit'

'set lat 25 45'
'set lon 100 130'
缩小点范围

我这样试过了，还是有问题
