Example

The following example demonstrates how to create a ChartControl with a series of the PolarPointSeriesView 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 a new chart.
    ChartControl polarPointChart = new ChartControl();

    // Add a polar series to it.
    Series series1 = new Series("Series 1", ViewType.PolarPoint);

    // Populate the series with points.
    series1.Points.Add(new SeriesPoint(0, 90));
    series1.Points.Add(new SeriesPoint(45, 70));
    series1.Points.Add(new SeriesPoint(90, 50));
    series1.Points.Add(new SeriesPoint(135, 100));
    series1.Points.Add(new SeriesPoint(180, 90));
    series1.Points.Add(new SeriesPoint(225, 70));
    series1.Points.Add(new SeriesPoint(270, 50));

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

    // Adjust the view-type specific properties of the series.
    PolarPointSeriesView myView = (PolarPointSeriesView)series1.View;

    myView.PointMarkerOptions.Kind = MarkerKind.Star;
    myView.PointMarkerOptions.StarPointCount = 5;
    myView.PointMarkerOptions.Size = 20;

    // Flip the diagram (if necessary).
    ((PolarDiagram)polarPointChart.Diagram).StartAngleInDegrees = 180;
    ((PolarDiagram)polarPointChart.Diagram).RotationDirection =
        RadarDiagramRotationDirection.Counterclockwise;

    // Add a title to the chart, and hide the legend.
    polarPointChart.Titles.Add(new ChartTitle());
    polarPointChart.Titles[0].Text = "A Polar Point Chart";
    polarPointChart.Legend.Visible = false;

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