Example
The following example demonstrates how to create a ChartControl with a series of the Doughnut3DSeriesView type, set its general properties, 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 DoughnutChart3D = new ChartControl();
// Create a doughnut series.
Series series1 = new Series("Doughnut Series 1", ViewType.Doughnut3D);
// Populate the series with points.
series1.Points.Add(new SeriesPoint("Russia", 17.0752));
series1.Points.Add(new SeriesPoint("Canada", 9.98467));
series1.Points.Add(new SeriesPoint("USA", 9.63142));
series1.Points.Add(new SeriesPoint("China", 9.59696));
series1.Points.Add(new SeriesPoint("Brazil", 8.511965));
series1.Points.Add(new SeriesPoint("Australia", 7.68685));
series1.Points.Add(new SeriesPoint("India", 3.28759));
series1.Points.Add(new SeriesPoint("Others", 81.2));
// Add the series to the chart.
DoughnutChart3D.Series.Add(series1);
// Adjust the value numeric options of the series.
series1.PointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
series1.PointOptions.ValueNumericOptions.Precision = 2;
// Adjust the view-type-specific options of the series.
((Doughnut3DSeriesView)series1.View).HoleRadiusPercent = 30;
((Doughnut3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[0]);
// Access the diagram's options.
((SimpleDiagram3D)DoughnutChart3D.Diagram).RotationType = RotationType.UseAngles;
((SimpleDiagram3D)DoughnutChart3D.Diagram).RotationAngleX = -35;
// Add a title to the chart and hide the legend.
ChartTitle chartTitle1 = new ChartTitle();
chartTitle1.Text = "3D Doughnut Chart";
DoughnutChart3D.Titles.Add(chartTitle1);
DoughnutChart3D.Legend.Visible = false;
// Add the chart to the form.
DoughnutChart3D.Dock = DockStyle.Fill;
this.Controls.Add(DoughnutChart3D);
