expression.ReplaceNode(TargetNode)
expression Required. An expression that returns a DiagramNode object.
TargetNode Required DiagramNode object. The diagram node to be replaced.
Example
The following example replaces the fourth diagram node of a newly-created diagram with the second node.
Sub Replace()
Dim dgnNode As DiagramNode
Dim shpDiagram As Shape
Dim intCount As Integer
'Add pyramid diagram to current document
Set shpDiagram = ThisDocument.Shapes.AddDiagram _
(Type:=msoDiagramPyramid, Left:=10, _
Top:=15, Width:=400, Height:=475)
'Add first child node to diagram
Set dgnNode = shpDiagram.DiagramNode.Children.AddNode
'Add three more child nodes
For intCount = 1 To 3
dgnNode.AddNode
Next intCount
'Replace fourth node with the second node
dgnNode.Diagram.Nodes(2).ReplaceNode _
TargetNode:=dgnNode.Diagram.Nodes(4)
End Sub
