Dear Hongyan,
There are a couple of ways you can do this.
One is to not use gsn_csm_attach_zonal_means, but to instead create the contour and XY plots yourself, and then use vpXXX resources to resize and position them as needed.
The other way is to use the special, and not very much mentioned, "NhlAddData" procedure, which allows you to add extra curves to an XY plot that already exists.
To do this requires more object oriented style coding. I've included an example that you should be able to run as is.
You will need to modify this block of code:
;---Set some resources for the new curve.
setvalues dataspec
"xyLineColor" : "NavyBlue"
"xyLineThicknessF" : 2.
end setvalues
to change how you want that extra curve to look.
And, of course, you will need to change this code to be whatever your X/Y values are for the new curve:
;---Create dummy data object to add new curve to zonal plot
x = (/ 0, 5,10, 15,20,25,30,35,40/)
y = (/-30,-20,0,-10,20,30,25,20,40/)
