The information in this article applies to:
In Microsoft Excel 97, you can associate a chart sheet in a workbook with a Visual Basic module. This means you can create a macro that runs when certain events occur on the chart sheet. However, this functionality does not apply to charts that are embedded on a worksheet.
This article contains sample macros that trap an event for an embedded chart.

1. Save and close any open workbooks, and then create a new workbook.
2. Type the following data in Sheet1:
A1: 1
A2: 2
A3: 3
4. In the "Chart Wizard - Step 1 of 4 - Chart Type" dialog box, click
Finish.
1. Start the Visual Basic Editor (press ALT+F11).
2. On the Insert menu, click Class Module.
3. In this class module, type the following code:
Public WithEvents EmbChart As Chart
The WithEvents keyword makes the EmbChart variable available
in the Object list in the Class1 (Code) module window.
4. In the Class1 (Code) window, click EmbChart in the Object list.
The following code automatically appears in the class module:
Private Sub EmbChart_Activate()
End Sub
NOTE: The Activate event is the default event for the object.
5. In the Class1 (Code) window, click Resize in the Procedure list.
The following code automatically appears in the class module:
Private Sub EmbChart_Resize()
End Sub
6. Change the Resize event procedure so that it looks like the following:
Private Sub EmbChart_Resize()
MsgBox "You are resizing the " & EmbChart.Name & " chart."
End Sub
7. On the Insert menu, click Module.
8. In this module, type the following code:
Dim mychart As New Class1
Sub Set_Chart()
Set mychart.EmbChart = Sheet1.ChartObjects(1).Chart
End Sub
9. Run the Set_Chart macro.
NOTE: If you have a Microsoft IntelliMouse and you use the scroll wheel on the mouse to scroll up or down the worksheet, the Resize event occurs if the chart is active and all or part of it is not visible on the screen.
10. Press ALT+F11 to switch to Microsoft Excel.
11. Click once on the embedded chart in Sheet1 to switch to it.
12. With your pointer, drag one of the handles on the border of the
chart in any direction.
You are resizing the Sheet1 Chart 1 chart.
If you close the workbook that contains the above project, the event handler is disabled. To programmatically disable the event handler, use the following steps:
1. Start the Visual Basic Editor.
2. In the general module in which you typed the Set_Chart macro, add the
following macro:
Sub Reset_Chart()
Set mychart.EmbChart = Nothing
End Sub
4. On the File menu, click "Close and Return to Microsoft Excel."
5. Select and resize the embedded chart.
The message box does not appear.
