[ncl-talk] Avoiding overwritten gsnCenterString

[Karin Meier-Fleischer]

Hi,

why not go the easiest way and write the center string just once and set 
the others to an empty string.

;**********************************
*   res at gsnCenterString     = "AMOnr PI"    ; change Center string*
    res at gsnLeftString       = "(b)"         ; change Left string
    res at gsnStringFontHeightF = 0.010

    res at xyLineColors        = (/"green4"/)  ; Line colours (white-to 
invisible the markov line)
    plot(2) = gsn_csm_xy(wks, p11, spec1 at spcx, res)

*   res at gsnCenterString     = ""*
    res at xyLineColors        = (/"red"/)     ; Line colours (white-to 
invisible the markov line)
    plot2 = gsn_csm_xy(wks, p21, spec2 at spcx, res)

*   res at gsnCenterString     = ""*
    res at xyLineColors        = (/"blue"/)    ; Line colours (white-to 
invisible the markov line)
    plot3 = gsn_csm_xy(wks, p31, spec3 at spcx, res)

    overlay(plot(2),plot2)
    overlay(plot(2),plot3)
;***************************************************

Bye
Karin
