      ' 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 OLE object.
            If oShape.Type = msoEmbeddedOLEObject Then

               ' Check whether the OLE object is a Graph 8 object.
               If oShape.OLEFormat.ProgID = "MSGraph.Chart.8" Then

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