Example

The following example demonstrates how to create a ChartControl with a series of the Funnel3DSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.

using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...

private void Form1_Load(object sender, EventArgs e) {
    // Create an empty chart.
    ChartControl funnelChart3D = new ChartControl();

    // Create a funnel series.
    Series series1 = new Series("Funnel Series 1", ViewType.Funnel3D);

    // Populate the series with points.
    series1.Points.Add(new SeriesPoint("A", 28.5));
    series1.Points.Add(new SeriesPoint("B", 19.6));
    series1.Points.Add(new SeriesPoint("C", 17.1));
    series1.Points.Add(new SeriesPoint("D", 12.5));
    series1.Points.Add(new SeriesPoint("E", 9.6));

    // Add the series to the chart.
    funnelChart3D.Series.Add(series1);

    // Display a title for the series, 
    // and adjust another view-type-specific options of the series.
    Funnel3DSeriesView funnelView = (Funnel3DSeriesView)series1.View;
    funnelView.Titles.Add(new SeriesTitle());
    funnelView.Titles[0].Text = series1.Name;
    funnelView.HeightToWidthRatio = 1;
    funnelView.HoleRadiusPercent = 70;
    funnelView.PointDistance = 5;

    // Adjust the value numeric options of the series.
    series1.PointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
    series1.PointOptions.ValueNumericOptions.Precision = 1;

    // Access the view-type-specific series options.
    ((FunnelPointOptions)series1.PointOptions).PercentOptions.ValueAsPercent = true;

    // Position the series labels.
    ((Funnel3DSeriesLabel)series1.Label).Position = 
        FunnelSeriesLabelPosition.LeftColumn;

    // Access the diagram's options.
    ((FunnelDiagram3D)funnelChart3D.Diagram).RuntimeRotation = true;
    ((FunnelDiagram3D)funnelChart3D.Diagram).RotationType = 
        RotationType.UseMouseStandard;

    // Hide the chart's legend.
    funnelChart3D.Legend.Visible = false;

    // Add the chart to the form.
    funnelChart3D.Dock = DockStyle.Fill;
    this.Controls.Add(funnelChart3D);
}
