Before you can run the sample Visual Basic macro, you must add a reference to the Microsoft Excel 9.0 object library model. To add the reference:

On the Tools menu, point to Macro, and then click Visual Basic Editor.

On the Tools menu, click References.

In the References - VBAProject dialog box, click to select the Microsoft Excel 9.0 Object Library check box.

Click OK.

You now have a reference (in this project) to the Graph 9.0 object model.

   Sub UpdateAllGraphs()

      Dim oShape As Shape
      Dim oSlide As Slide
      Dim oGraph As Object

      ' Loop through each slide in the presentation.
      For Each oSlide In ActivePresentation.Slides

         ' Loop through all the shapes on the current slide.
         For Each oShape In oSlide.Shapes

            ' Check whether the shape is an Excel linked OLE object.
            If oShape.Type = msoLinkedOLEObject Then

               ' Check whether the OLE object is a Chart or a Sheet object.
               If oShape.OLEFormat.ProgID = "Excel.Chart.9" _
               Or oShape.OLEFormat.ProgID = "Excel.Sheet.9" Then

                  ' Found a Chart; obtain object reference, and
                  ' then update.
                  Set oGraph = oShape.OLEFormat.Object
                  oGraph.Application.Update

               End If
            End If
