'Declaration Public Overrides Property Chart As ChartType
public override ChartType Chart {get; set;}
The Polyline requires all of its constituent Primitives to have the same ChartType as itself, therefore this method overrides the base behavior to update its child Primitives.
Primitives may become invalidated if the ChartType of the control has changed. Always call the Clear method of the SceneGraph prior to changing ChartType.
