expression.SwapNode(pTargetNode, swapChildren)
expression Required. An expression that returns one of the objects in the Applies To list.
pTargetNode Required DiagramNode object. The target diagram node to be replaced.
swapChildren Optional Boolean. The child nodes of the target and source nodes being swapped. Any child diagram nodes are moved along with their corresponding root nodes. Default is True, which swaps the child nodes.
Example
The following example swaps the second diagram node of a newly-created diagram with the last node.
Sub SwapNode()
Dim nodRoot As DiagramNode
Dim nodPrev As DiagramNode
Dim shDiagram As Shape
Dim intCount As Integer
Set shDiagram = ActiveSheet.Shapes.AddDiagram _
(Type:=msoDiagramRadial, Left:=10, Top:=15, _
Width:=400, Height:=475)
Set nodRoot = shDiagram.DiagramNode.Children.AddNode
' Add 3 child nodes to the root node.
For intCount = 1 To 3
nodRoot.Children.AddNode
Next
' Swap the second node with the fourth node.
nodRoot.Children.Item(2).SwapNode _
pTargetNode:=nodRoot.Diagram.Nodes(4), _
swapChildren:=True
End Sub
