Examples

The following code example creates a Chart and then uses the ApplyDataLabels method to display data labels with the series names on the chart.

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

    Dim Chart1 As Microsoft.Office.Tools.Excel.Chart = _
        Me.Controls.AddChart(Me.Range("D2", "H20"), "Chart1")

    Chart1.SetSourceData(Me.Range("A1", "B5"), Excel.XlRowCol.xlColumns)
    Chart1.ChartType = Excel.XlChartType.xlBarClustered

    Chart1.ApplyDataLabels(Excel.XlDataLabelsType.xlDataLabelsShowLabel, _
        False, False, False, True, False, False, False, False, False)
End Sub

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

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(this.Range["D2", "H20"], 
        "chart1");

    chart1.SetSourceData(this.Range["A1", "B5"], 
        Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xlBarClustered;

    chart1.ApplyDataLabels(
        Excel.XlDataLabelsType.xlDataLabelsShowLabel,
