    Liping (and Adam),

    Just a tiny correction, be sure to remove the line:

             "gsnXRefLine": 0.0 ; draw a reference line

    from the "setvalues" block. The gsn resources are special ones that
    are recognized only by the gsn plotting scripts, and are *not*
    recognized by setvalues.
