SUMMARY
This article provides a sample Microsoft Visual Basic for Applications macro (Sub procedure) that creates a Microsoft PowerPoint presentation containing five slides. On each slide, a graph is created using a different chart type, such as pie, column, and so on.



MORE INFORMATION
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. Before you can run the sample Visual Basic macro, you must add a reference to the Graph 8.0 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 8.0 Object Library" check box.
 * 4) Click OK.

You now have a reference (in this project) to the Graph 8.0 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
