Chart.GetChartElement method (Excel)
Returns information about the chart element at specified x and y coordinates. This method is unusual in that you specify values for only the first two arguments. Microsoft Excel fills in the other arguments, and your code should examine those values when the method returns.
Syntax
expression.GetChartElement (x, y, ElementID, Arg1, Arg2)
expression A variable that represents a Chart object.
Parameters
| Name | Required/Optional | Data type | Description |
|---|---|---|---|
| x | Required | Long | The x coordinate of the chart element. |
| y | Required | Long | The y coordinate of the chart element. |
| ElementID | Required | Long | When the method returns, this argument contains the XLChartItem value of the chart element at the specified coordinates. For more information, see the Remarks section. |
| Arg1 | Required | Long | When the method returns, this argument contains information related to the chart element. For more information, see the Remarks section. |
| Arg2 | Required | Long | When the method returns, this argument contains information related to the chart element. For more information, see the Remarks section. |

Example
This example warns the user if she moves the mouse over the chart legend.
Private Sub Chart_MouseMove(ByVal Button As Long, _
ByVal Shift As Long, ByVal X As Long, ByVal Y As Long)
Dim IDNum As Long
Dim a As Long
Dim b As Long
ActiveChart.GetChartElement X, Y, IDNum, a, b
If IDNum = xlLegendEntry Then _
MsgBox "WARNING: Move away from the legend"
End Sub
