NOTE: This macro counts Graph 8 objects when you are using slide view.

Sample Visual Basic Procedure

Sub CountGraphs()

   ' Dimension the variables.
   Dim shapeObject As Shape
   Dim lSlideNumber As Long
   Dim lCount As Long
   Dim strPrompt As String
   Dim strTitle As String
   Dim lBoxStyle As Long

   ' Make sure PowerPoint is using slide view.
   If ActiveWindow.ViewType <> ppViewSlide Then

      MsgBox "You must be in slide view to run this macro."
      End

   End If

   ' Initialize the counter.
   lCount = 0

   ' Get the current slide number.
   lSlideNumber = ActiveWindow.Selection.SlideRange.SlideNumber

   ' Look at all shapes on the current slide.
   For Each shapeObject In _
      ActivePresentation.Slides(lSlideNumber).Shapes

      ' Check to see whether shape is an OLE object.
      If shapeObject.Type = msoEmbeddedOLEObject Then

         ' Check to see whether OLE object is Graph 8 object. The ProgID
         ' is case sensitive.
         If shapeObject.OLEFormat.ProgID = "MSGraph.Chart.8" Then

            ' Found a graph; add 1 to the total.
            lCount = lCount + 1
         End If

      End If

   Next shapeObject

   ' Creates and then displays the message box.

   ' Set the message box style.
   lBoxStyle = vbInformation

   Select Case lCount

      ' No graphs were found.
      Case 0
         strPrompt = "No graphs were found on the slide."
         strTitle = "No graphs"

      ' One graph was found.
      Case 1
         strPrompt = "One graph was found on the slide."
         strTitle = "One Graph"

      ' More than one graph was found.
      Case Is > 1
         strPrompt = lCount & " Graphs were found on the slide."
         strTitle = lCount & " Graphs"

      ' An error occurred.
      Case Else
         strPrompt = "An error occurred!"
         strTitle = "Error"
         lBoxStyle = vbCritical
   End Select

   'Display the message box.
   MsgBox strPrompt, lBoxStyle, strTitle
