[ncl-talk] About contour line thickness

[zuibeidemei]

Hi Adam:

 Thanks for your reply.

 The disired figure is a contour figure with color filled and only one zero line visible, (cnFillOn =True cnLinesOn=True)
         
           Just setting cnlevels = 0 may hurt the display of the color part.

 I tried to minimize the cnLineThickness (like 1e-10) and make it unvisible,


           but maximize the zero line thickness (10), with the following res.

 res at cnLineThicknessF     = 1e-10

        res at gsnContourZeroLineThicknessF =10

           But this combination fails.

Hi Cheung,

I would recommend setting cnLevelSelectionMode = "ExplicitLevels" and setting cnLevels = 0.


See example #4 here:

Hope that helps. If not, please respond to the ncl-talk email list.

Dear all:

 I'd like plot a contour figure with only a zero line displayed, and lines of all other contour levels are ignored.

        I tried with the following res with several values combination but it doesn't work. Can anyone give a help?

 res at cnLineThicknessF 
 res at gsnContourLineThicknessesScale 
        res at gsnContourZeroLineThicknessF
