The following example demonstrates how to create a ChartControl with a series of the PolarLineSeriesView 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 polarLineChart = new ChartControl();

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

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

    // Add the series to the chart.

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

    // Add a title to the chart and hide the legend.
    ChartTitle chartTitle1 = new ChartTitle();
    chartTitle1.Text = "Polar Line Chart";
    polarLineChart.Legend.Visible = false;

    // Add the chart to the form.
    polarLineChart.Dock = DockStyle.Fill;
