[mapguide-users] show one symbol for each polygon.

You might have to get the centroids of the polygons using your dataset first.  

For example, if you are using Oracle spatial, 
select SDO_GEOM.SDO_CENTROID(mygeom,0.005) as myCentoidGeom from
mySpatialTable

or if you are using SQL Server:

select mygeom.STCentroid() as myCentroidGeom from mySpatialTable

and so on…

ps. You can create a view doing this and then you will have to either apply
a constraint (Oracle) or SCHEMABINDING with index (SQL Server) or use
Jackie's technique of overriding the schema but you have to do this each
time your database changes -

It would be nice to do Schema Overrides within Maestro (or Studio)….
