Does anyone know a good way to handle z ordering when using GraphicTracker in ArcEngine?

Question

From the GraphicTracker Documentation:

The first graphic added will appear underneath subsequent graphics if they have overlapping display areas.

This is not true when using ArcEngine 10.0 with polygon fill symbols on picture marker symbols - sometimes it works (1st time for sure) and sometimes it does not.

Has anyone figured out a proper way to manage z ordering of symbols when using ArcEngine and using GraphicTracker?

Answer 1

ESRI gave me the correct answer to this - you need to manage ordering use the multiple instances of the GraphicTracker - any subsequent GraphicTracker will have its graphics overlap over any previous instance of GraphicTracker's graphics. There is no guarantee of ordering of graphics within a single instance of a GraphicTracker instance.
