_Chart.GetChartElement Method
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.
Namespace: Microsoft.Office.Interop.Excel
Assembly: Microsoft.Office.Interop.Excel (in Microsoft.Office.Interop.Excel.dll)

Parameters
x
Type: System.Int32Required Integer. The X coordinate of the chart element.
y
