WithEvents MouseMoveChart As Microsoft.Office.Tools.Excel.Chart

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

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

Sub MouseMoveChart_MouseMove(ByVal Button As Integer, _
    ByVal Shift As Integer, ByVal x As Integer, _
    ByVal y As Integer) Handles MouseMoveChart.MouseMove

    Me.Range("D14").Value2 = "The mouse is moving over the chart."
End Sub

private void DisplayMouseMove()
{
    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);
    chart1.ChartType = Excel.XlChartType.xl3DColumn;

    chart1.MouseMove +=
        new Excel.ChartEvents_MouseMoveEventHandler(
        chart1_MouseMove);
}

void chart1_MouseMove(int Button, int Shift, int x, int y)
{
    this.Range["D14", missing].Value2 = 
        "The mouse is moving over the chart.";
