Q: How to perform avoid function when the Label map and the Graph map are displayed simultaneously?

Be default, the IsTextOrientationFixed property of Map class is true, which indicates some texts are unable to be displayed on a map. When the Label map and Graph map are displayed simultaneously, or multi-layers exist in the same map, the display effect of the map depends on the sequence of layers added to the map. If the IsTextOverlapAvoided property is set to false, the overlapped texts can be displayed.
