RadarPointSeriesView Class

Represents a series view of the Radar Point type.

Assembly: DevExpress.XtraCharts.v21.2.dll

Declaration

C#
VB.NET

public class RadarPointSeriesView :
    RadarSeriesViewBase,
    IPointSeriesView

Public Class RadarPointSeriesView
    Inherits RadarSeriesViewBase
    Implements IPointSeriesView

Remarks

The RadarPointSeriesView class provides the functionality of a series view of the Radar Point type within a chart control. At the same time, the RadarPointSeriesView class serves as a base for the RadarLineSeriesView and RadarAreaSeriesView classes and so provides the common functionality for Radar Series Views.

In addition to the common view settings inherited from the base RadarSeriesViewBase class, the RadarPointSeriesView class declares specific point type settings which allow you to define the settings of point markers (RadarPointSeriesView.PointMarkerOptions).

Note that a particular view type can be defined for a series using its SeriesBase.View property.

For more information, refer to Radar Point Chart.

Example

The following example demonstrates how to create a ChartControl with a series of the RadarPointSeriesView 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.

C#
VB.NET

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

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl RadarPointChart = new ChartControl();

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

    // Populate the series with points.
    series1.Points.Add(new SeriesPoint(0, 90));
    series1.Points.Add(new SeriesPoint(90, 95));
    series1.Points.Add(new SeriesPoint(180, 50));
    series1.Points.Add(new SeriesPoint(270, 55));
    series1.Points.Add(new SeriesPoint(0, 180));
    series1.Points.Add(new SeriesPoint(90, 185));
    series1.Points.Add(new SeriesPoint(180, 270));
    series1.Points.Add(new SeriesPoint(270, 275));

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

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

    // Add a title to the chart and hide the legend.
    ChartTitle chartTitle1 = new ChartTitle();
    chartTitle1.Text = "Radar Point Chart";
    RadarPointChart.Titles.Add(chartTitle1);
    RadarPointChart.Legend.Visible = false;

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