        this.Controls.AddChart(this.Range["D2", "H12"], 
        "chart1");

    chart1.SetSourceData(this.Range["A1", "B5"], 
        Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xl3DColumn;

    chart1.DisplayBlanksAs = 
        Excel.XlDisplayBlanksAs.xlNotPlotted;
}

Private Sub DisableBlankPlotting()
    ' Note that the following data ranges are missing 
    ' values in A5 and B1.
    Me.Range("A1", "A4").Value2 = 22
    Me.Range("B2", "B5").Value2 = 55

    Dim Chart1 As Microsoft.Office.Tools.Excel.Chart = _
        Me.Controls.AddChart(Me.Range("D2", "H12"), "Chart1")

    Chart1.ChartType = Excel.XlChartType.xl3DColumn

    Chart1.DisplayBlanksAs = Excel.XlDisplayBlanksAs.xlNotPlotted
