Re: how to plot this contour map

Hi Hongyan,

I think you are looking for the similar method used in example
http://www.ncl.ucar.edu/Applications/Scripts/ce_2.ncl

cnLevelSelectionMode = "ManualLevels"
cnMinLevelValF = -10.
cnMaxLevelValF = 35.
cnLevelSpacingF = 5., manually sets the contour levels.

see more examples @ http://www.ncl.ucar.edu/Applications/cylineq.shtml

Also, please check Contours Plot Type Examples @
http://www.ncl.ucar.edu/Applications/list_ptypes.shtml

Hope this helps.
