Hi Keith,

You can only have one type of marker per curve, and in your gsn_csm_xy
call below, it thinks you just have one curve, so it only uses one marker

To make gsn_csm_xy see these as multiple curves, you need to give it
an ncurves x npts arrays, where ncurves will be 50, in your case,
and npts will be 1.

I hope this will work as I'm not sure I've tried gsn_csm_xy with one-point
curves.

Try this:

   riv_data!0 = "npts"
   riv_data!1 = "ncurves"
   ...
    plot = gsn_csm_xy(wks,riv_data(ncurves | 0:49, npts | 1), \
                          riv_data(ncurves | 0:49, npts | 3),res)
