Re: Re : Line thickness

Another approach:

The following is untested

    res_at_gsnDraw = False
    res_at_gsnFrame= False

    plot = ....

    getvalues plot
        "cnLevels" : cnlvls
        "cnLineDashPatterns" : cnlinepat
        "cnLineThicknesses" : cnlinethk
        "cnLineColors" : cnlinecolor
    end getvalues

    ii = ind(cnlvls.eq. -2.0)

    if (.not.ismissing(ii)) then
       ;cnlinepat(ii) = 5 ; simple dash line
        cnlinethk(ii) = 2 ; make twice as thick
       ;cnlinecolor(ii) = 2 ; index or (say) "red"
    end if

    setvalues plot
      ;"cnMonoLineDashPattern" : False
      ;"cnLineDashPatterns" : cnlinepat
       "cnMonoLineThickness" : False
       "cnLineThicknesses" : cnlinethk
      ;"cnMonoLineColor" : False
      ;"cnLineColors" : cnlinecolor

    end setvalues

    draw(plot)
    frame(wks)

===========
Youc could use the above approach to change colors
