NCL绘制不带源边框的地图

Question

我正在使用Debian下的NCL 6.6.2，并且不想创建一些投影图像。如何防止在地图周围绘制边框。我现在找不到合适的属性。

begin

  wks  = gsn_open_wks("png","map1")  ; send graphics to PNG file

  res                       = True
  res@gsnFrame              = False  ; <-- This seems not to work because it draw nothing at all.

  res = True;
  res@mpProjection               = "Satellite" ; choose map projection
  res@mpCenterLonF               = 13.         ; choose center lon
  res@mpCenterLatF               = 54.         ; choose center lat
  res@mpSatelliteDistF           = 3.0         ; choose satellite view
  res@mpOutlineOn                = False       ; 
  res@mpGridAndLimbOn        = True
  res@mpDataBaseVersion      = "MediumRes"  

  col = (/ .20, 0.20, 0.30, .8/)
  res@mpLandFillColor        = col
  res@mpOceanFillColor       = "White"
  res@mpInlandWaterFillColor = col

  plot = gsn_csm_map(wks, res)  ; draw satellite proj map
end

因为您已经设置了@gsnFrame=False，所以NCL暂时不会绘制。

如何修复它？

最后，添加：

frame(wks)
draw(plot)
