Private Sub UseLineGroups()
    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", "H12"), "Chart1")

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

        Excel.ChartGroup)

    group.HasDropLines = True 
End Sub

private void UseLineGroups()
{
    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"],
