      'At this point, the active sheet is a Chart sheet with a column chart
      'and ActiveSheet.Name will return "Chart1" as a string value.

      'Because the variable mysheet picks up the name of the activesheet
      'before the chart sheet is created, you will not unexpectedly quit
      'using the variable.

      ActiveChart.Location _
         where:=xlLocationAsObject, Name:=mysheet
   End Sub
