Sample Visual Basic Procedure
Sub CreateGraphFromFile

Dim oGraph As Object Dim oDataSheet As Object Dim shpGraph As PowerPoint.Shape Dim lRowCnt As Long Dim lColCnt As Long Dim lValue As Long

' Add the graph to the slide. With ActivePresentation.Slides(1) ' Create the Graph object on the slide. Set shpGraph = .Shapes.AddOLEObject(ClassName:="MSGraph.Chart", _                                          Link:=msoFalse) End With

' Set references. Set oGraph = shpGraph.OLEFormat.Object Set oDataSheet = oGraph.Application.DataSheet

' Place headers into data table. ' Create four column headers. oDataSheet.Cells(1, 2).Value = "Col1" oDataSheet.Cells(1, 3).Value = "Col2" oDataSheet.Cells(1, 4).Value = "Col3" oDataSheet.Cells(1, 5).Value = "Col4"

' Create four row headers. oDataSheet.Cells(2, 1).Value = "Row1" oDataSheet.Cells(3, 1).Value = "Row2" oDataSheet.Cells(4, 1).Value = "Row3" oDataSheet.Cells(5, 1).Value = "Row4"

' We already know the number of columns and rows ' from the data we are importing. Open "" For Input As #1

' Get four rows of data. For lRowCnt = 2 To 5 For lColCnt = 2 To 5

' Get value from file. Input #1, lValue

' Place in data table. oDataSheet.Cells(lRowCnt, lColCnt).Value = lValue Next lColCnt Next lRowCnt Close #1 oDataSheet.Application.Update ' Release the reference. Set oGraph = Nothing Set oDataSheet = Nothing

End Sub
