    Me.Range("A1", "A5").Value2 = 22
    Me.Range("B1", "B5").Value2 = 55

    MouseDownChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
        "MouseDownChart")
    MouseDownChart.SetSourceData(Me.Range("A1", "B5"), _
        Excel.XlRowCol.xlColumns)
    MouseDownChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub

Sub MouseDownChart_MouseDown(ByVal Button As Integer, _
    ByVal Shift As Integer, ByVal x As Integer, _
    ByVal y As Integer) Handles MouseDownChart.MouseDown

    Me.Range("D14").Value2 = _
        "The chart was clicked at coordinates " _
        & x.ToString() & ", " & y.ToString()
End Sub

private void DisplayMouseDown()
{
    this.Range["A1", "A5"].Value2 = 22;
    this.Range["B1", "B5"].Value2 = 55;

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(this.Range["D2", "H12"], 
        "chart1");
    chart1.SetSourceData(this.Range["A1", "B5"], 
        Excel.XlRowCol.xlColumns);
