DiagramNode Object

Represents a single diagram node within a diagram.  The DiagramNode object is a member of the DiagramNodes collection.

Using the DiagramNode object

Use the DiagramNode property of the Shape or ShapeRange object to return a DiagramNode object. Use the AddNode method to add a node to a diagram. This example assumes the third shape in the document is a diagram and adds a node to it.

Sub AddDiagramNode()
    ActiveDocument.Shapes(3).DiagramNode.Children.AddNode
End Sub

Use the Delete method to remove a node from a diagram. This example assumes the second shape in the document is a diagram and removes the first node from it.

Sub DeleteDiagramNode()
    ActiveDocument.Shapes(2).DiagramNode.Children(1).Delete
End Sub
