Configures the chart diagram as a 3D funnel diagram.
public void FunnelDiagram3D( Action<FunnelDiagram3D> diagramAction )
Public Sub FunnelDiagram3D( diagramAction As Action(Of FunnelDiagram3D) )
A delegate method configuring the Funnel Diagram 3D object.
We recommend using this method after series are specified, because when the first series is added to a chart, the diagram type is changed to be compatible with the series view type.
If a chart doesn't have a specified diagram, this method sets it, and if a chart already has a specified diagram of another type, this method throws an exception.
