      {
         ChartObject chart = null;
      
         try
         {
            chart =
               (ChartObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
         }
         catch (Exception e)
         {
         }
         return chart;
      }
      

  
[Visual Basic]
      Private Function GetChartObject _
         (ByVal reportObjectName As String) As ChartObject
      
         Dim chart As ChartObject
      
         If TypeOf _
            (Report.ReportDefinition.ReportObjects. _
            Item(reportObjectName)) Is ChartObject Then
            chart = _
               Report.ReportDefinition.ReportObjects. _
               Item(reportObjectName)
            GetChartObject = chart
         Else : GetChartObject = Nothing
         End If
      End Function
      

  
[C#]
