Re: Small/Medium Circles..

For filled circles you can use poly marker index 16, or for an empty circle you can use index 4. You can control the size using gsMarkerSizeF. See http://www.ncl.ucar.edu/Applications/polyg.shtml, example 8.

So for example when is closer to the water I expect the width of the marker to be bigger and smaller as it approaches closer to land. Is there any function that shapes markers according to lat lon and radius.
