Before you can run the sample Visual Basic macro, you must add a reference to the Graph 9.0 object model. Follow these steps to add the reference:


 * 1) On the Tools menu, point to Macros, and then click Visual Basic Editor.
 * 2) On the Tools menu, click References.
 * 3) In the References - VBAProject dialog box, click to select the Microsoft Graph 9.0 Object Library check box.
 * 4) Click OK. You now have a reference (in this project) to the Graph 9.0 object model.

Sample Visual Basic Procedure
Sub ChangeChartType

Dim oGraphShape As PowerPoint.Shape Dim oGraph As Graph.Chart

' Set up an array to hold different chart types. Dim lChartTypeArray(1 To 5) As Long

' Populate the array with different chart types. lChartTypeArray(1) = xl3DPie lChartTypeArray(2) = xl3DColumn lChartTypeArray(3) = xlBubble3DEffect lChartTypeArray(4) = xlPyramidBarStacked lChartTypeArray(5) = xlSurfaceTopView

' Create a new presentation. Dim oPres As PowerPoint.Presentation Set oPres = PowerPoint.Presentations.Add

Dim x As Long For x = 1 To 5

' Create a new slide. oPres.Slides.Add x, ppLayoutBlank

With oPres.Slides(x)

' Create the Graph object. Set oGraphShape = .Shapes _ .AddOLEObject(0,0,oPres.PageSetup.SlideWidth, _              oPres.PageSetup.SlideHeight, _               "MSGraph.Chart", _               Link:=msoFalse)

End With

' Get an object reference to the Graph you just created. Set oGraph = oGraphShape.OLEFormat.Object

' Set the chart type. oGraph.ChartType = lChartTypeArray(x)

' Release the reference. Set oGraph = Nothing

Next x

End Sub
