Re: x3y3 plot

Hi Jam,

We don't have an example of this, unfortunately, and it's not trivial.

I don't have time to come up with an example right away, but
here's an outline of how you might do this:

   - Call gsn_csm_x2y2 to create two of the curves:

      plot12 = gsn_csm_x2y2(wks,x1,x2,y1,y2,res1,res2)

     Be sure to set trMin/MaxX/F resources to get the X/Y axis limits exactly
     as you want them.

   - Call gsn_csm_xy to create the third curve, setting
     tfDoNDCOverlay to True in the resource list (ovrly_plot).

      plot3 = gsn_csm_xy(wks,x3,y3,res3)

     Again, set trMin/MaxX/F resources to get the X/Y axis limits
     exactly as you want them.

         You will need to set any necessary resources to turn off
     titles and perhaps other annotations you don't want.

   - Overlay the the plots:

       overlay(plot12,plot3)

   - Attach single vertical and horizontal axes to represent third curve.
     You can see a sample of how this is done for a Y axis in example

       http://www.ncl.ucar.edu/Applications/xy.shtml#ex27

   - Once you have all this:

        draw(plot12)
        frame(wks)

If this is too hard to figure out, let me know and I'll try to come up
with an example when I have time.
