Hi Lyndon,<br>
<br>
the problem is that your shapefile data does not contain point data
which is needed by gsn_add_shapefile_polymarkers function <br>
<br>
<font color="#3333ff"><a class="gmail-m_6400829349194253848moz-txt-link-freetext" href="http://ncl.ucar.edu/Document/Graphics/Interfaces/gsn_add_shapefile_polymarkers.shtml" target="_blank">http://ncl.ucar.edu/Document/<wbr>Graphics/Interfaces/gsn_add_<wbr>shapefile_polymarkers.shtml</a></font><br>
<br>
To see what is in your shapefile you can draw the shapefile data
using the x- and y-values. I've attached your modified script and
the PNG plot.<br>

Karin<br>
