Following is my code:

protected void Page_Load(object sender, EventArgs e)
    {
        ultraChart.ChartType = ChartType.Composite;
        ultraChart.EnableCrossHair = true;
 
 
        ChartArea myChartArea = new ChartArea();
        ultraChart.CompositeChart.ChartAreas.Add(myChartArea);
 
        AxisItem axisX = new AxisItem();
        axisX.OrientationType = AxisNumber.X_Axis;
        axisX.DataType = AxisDataType.String;
        axisX.SetLabelAxisType = SetLabelAxisType.GroupBySeries;
        axisX.Labels.ItemFormatString = "<ITEM_LABEL>";
        axisX.Labels.Orientation = TextOrientation.VerticalLeftFacing;
 
        AxisItem axisY = new AxisItem();
        axisY.OrientationType = AxisNumber.Y_Axis;
        axisY.DataType = AxisDataType.Numeric;
        axisY.Labels.ItemFormatString = "<DATA_VALUE:0.#>";
 
        myChartArea.Axes.Add(axisX);
        myChartArea.Axes.Add(axisY);
 
        NumericSeries seriesA = GetNumericSeriesBound();
        NumericSeries seriesB = GetNumericSeriesUnBound();
        ultraChart.CompositeChart.Series.Add(seriesA);
        ultraChart.CompositeChart.Series.Add(seriesB);
 
        ChartLayerAppearance myColumnLayer = new ChartLayerAppearance();
        myColumnLayer.ChartType = ChartType.ColumnChart;
        myColumnLayer.ChartArea = myChartArea;
        myColumnLayer.AxisX = axisX;
        myColumnLayer.AxisY = axisY;
        myColumnLayer.Series.Add(seriesA);
        myColumnLayer.Series.Add(seriesB);
        ultraChart.CompositeChart.ChartLayers.Add(myColumnLayer);
 
 
        CompositeLegend myLegend = new CompositeLegend();
        myLegend.ChartLayers.Add(myColumnLayer);
        myLegend.Bounds = new Rectangle(0, 75, 20, 25);
        myLegend.BoundsMeasureType = MeasureType.Percentage;
        myLegend.PE.ElementType = PaintElementType.Gradient;
        myLegend.PE.FillGradientStyle = GradientStyle.ForwardDiagonal;
        myLegend.PE.Fill = Color.CornflowerBlue;
        myLegend.PE.FillStopColor = Color.Transparent;
        myLegend.Border.CornerRadius = 10;
        myLegend.Border.Thickness = 0;
        ultraChart.CompositeChart.Legends.Add(myLegend);
 
    }
 
    private static DataTable GetData()
    {
        DataTable table = new DataTable();
        table.Columns.Add("Label Column"typeof(string));
        table.Columns.Add("Value Column"typeof(double));
        table.Columns.Add("Another Value Column"typeof(double));
        table.Rows.Add(new object[] { "Point A", 1.0, 3.0 });
        table.Rows.Add(new object[] { "Point B", 2.0, 2.0 });
        table.Rows.Add(new object[] { "Point C", 3.0, 1.0 });
        table.Rows.Add(new object[] { "Point D", 4.0, 2.0 });
        table.Rows.Add(new object[] { "Point E", 5.0, 3.0 });
        return table;
    }
 
    private static NumericSeries GetNumericSeriesBound()
    {
        NumericSeries series = new NumericSeries();
        series.Label = "Series A";
        // this code populates the series from an external data source
        DataTable table = GetData();
        series.Data.DataSource = table;
        series.Data.LabelColumn = "Label Column";
        series.Data.ValueColumn = "Value Column";
        return series;
    }
    private static NumericSeries GetNumericSeriesUnBound()
    {
        NumericSeries series = new NumericSeries();
        series.Label = "Series B";
        // this code populates the series using unbound data
        series.Points.Add(new NumericDataPoint(5.0, "Point A"false));
        series.Points.Add(new NumericDataPoint(4.0, "Point B"false));
        series.Points.Add(new NumericDataPoint(3.0, "Point C"false));
        series.Points.Add(new NumericDataPoint(2.0, "Point D"false));
        series.Points.Add(new NumericDataPoint(1.0, "Point E"false));
