GeoGetPolygonCenter - script and chart function

GeoGetPolygonCenter() is used in scripts and chart expressions to calculate and return the center point of a geometry.

In some cases, the requirement is to plot a dot instead of color fill on a map. If the existing geospatial data is only available in the form of area geometry (for example, a boundary), use GeoGetPolygonCenter() to retrieve a pair of longitude and latitude for the center of area.

Syntax:  

GeoGetPolygonCenter(field_name)

Return data type: string

Arguments:  

Argument Description
field_name A field or expression referring to a field containing the geometry to be represented. This could be either a point (or set of points) giving longitude and latitude, or an area.
Tip: Do not use the Group by clause in the data load editor with this and other non-aggregating geospatial functions, because this will cause an error on load.
