I have the following macro:

Private Sub Worksheet_Calculate()
If ThisWorkbook.Name = ActiveWorkbook.Name Then
Application.ScreenUpdating = False
If ChartObjects.Count 0 Then
With ChartObjects(ChartObjects.Count)
AxisScale .Chart
End With
End If
Application.ScreenUpdating = True
End If
End Sub

I want it to only run when for the worksheet that it's "attached" to. It
seems to be running whenever I change anything on another worksheet in the
workbook. What do I need to change?

Thanks in advance,
Barb Reinhardt
