I'm sure there are better ways but

   [1] scale the y-values by * 1e5/1e9/1e12
       Then have a legend that has
  
  data = new ( (/3,N/),"float")
  data(0,:) = ya*1e5
  data(1,:) = yb*1e9
  data(2,:) = yc*1e12
  data_at_long_name = "..."
 ;data_at_units = "scaled"

  res = True ; plot mods desired
  res_at_pmLegendDisplayMode = "Always" ; turn on legend

  res_at_pmLegendSide = "Top" ; Change location of
  res_at_pmLegendParallelPosF = .45 ; move units right
  res_at_pmLegendOrthogonalPosF = -0.4 ; move units down

  res_at_pmLegendWidthF = 0.15 ; Change width and
  res_at_pmLegendHeightF = 0.18 ; height of legend.
  res_at_lgLabelFontHeightF = .03 ; change font height
  res_at_lgTitleOn = True ; turn on legend title
  res_at_lgTitleString = "scale" ; create legend title
  res_at_lgTitleFontHeightF = .025 ; font of legend title
  res_at_xyExplicitLegendLabels = (/"10^5","10^9","10^12"/)
  res_at_xyLineColors = (/"blue","red","green"/)

  plot=gsn_csm_xy(wks,x,data,res)
       
   [2] use gsn_csm_xy3

good luck
