Description

Adds the symbol and geomety to be tracked and returns an integer used to identify the graphic. Only geometries which support IPoint, IPolyline and IPolygon can be added. The Graphic Tracker holds an internal copy of each geometry and symbol supplied to it. The symbol must be appropriate for the geometry type; i.e. use fill symbols, not point symbols, to represent polygon geometries.The first graphic added will appear underneath subsequent graphics if they have overlapping display areas.
