Use something like Example 2 at
http://www.ncl.ucar.edu/Applications/xy.shtml

x1[*], y1[*]
x2[*], y2[*]
n1 = dimsizes(y1)
n2 = dimsizes(y2)
N = max( (/n1,n2/) )

xx = new((/2,N/),typeof(y1))
yy = new((/2,N/),typeof(y1))

xx(0:n1-1) = (/ x1 /)
yy(0:n1-1) = (/ y1 /)
xx(0:n2-1) = (/ x2 /)
xx(0:n2-1) = (/ y2 /)

;************************************************
wks = gsn_open_wks ("ps","xy") ; open workstation

res = True ; plot mods desired
res@tiMainString = "Mulitple XY plot" ; add title
res@xyLineThicknesses = (/1.0,2.0/) ; specify thickness
res@xyLineColors = (/"blue","red"/) ; change line color
;res@tiMainString = "..."
;res@gsnLeftString = "..."
;res@gsnCenterString = "..."
;res@gsnRightString = "..."

plot = gsn_csm_xy (wks,xx,yy,res) ; create plot
