[gradsusr] Wrong result when plotting hoop shapes

[yaqiang.wang at gmail.com]

At present, the GrADS interface does not draw polygons with more than one ring properly (http://www.iges.org/grads/gadoc/shapefiles.html). You can try other sotwares such as ArcGIS or MeteoInfo to plot hoop shapes.

Subject: [gradsusr] Wrong result when plotting hoop shapes
Hello,

I'm trying to plot shapes around some islands to mark the coasts. I have created a shapefile with all the shapes but I get a wrong result when trying to plot a hoop shape around a small island, all the shape is filled by color, the center of the island too. Only the coast should be filled, not the island, and I'm wondering if this is a GrADS bug or there is something that I'm doing in the wrong way. The result is attached in the mail.

Thanks in advance,

Oriol Ciurana
