Polar Series of Chart for WinForms C# Tutorial

The Series Types of Chart View is a collection of Chart Series, including Area, SplineArea, Bar, Line, Spline, Scatter point, Combined series. The Chart control provides two primary functions to Chart series. One is a collection used to stand for the specific data and the other is to visualize the data by using a predefined model. The following are the series types that the Chart support, including Bar, Pie, Line, Area, Donut, Scatter, Polar, Stock, Radar, Categorical or Polar.

The Polar series is only valid in the context of Polar AreaType. It contains a variety of classes used to plot data in radial plot area in polar coordinates. There are three significant implementations in the Polar series, PolarLineSeries, PolarAreaSeries and PolarPointSeries. If we use the polar series in unbound mode, it will be filled with PolarDataPoint objects. There are two properties, Angle and Value, in the object. The properties of Angle and Value are used to control the position of the points in the polar coordinate system through the polar and numeric radial axes. The following C# code shows different Polar series like polar point series, polar line series, and polar area series.

this.Chart1.AreaType = ChartAreaType.Polar;
PolarAreaSeries polarAreaSeries = new PolarAreaSeries();

PolarDataPoint polarPoint = new PolarDataPoint();
polarPoint.Value = 80;
polarPoint.Angle = 150;
polarAreaSeries.DataPoints.Add(polarPoint);

polarPoint = new PolarDataPoint();
polarPoint.Value = 140;
polarPoint.Angle = 90;
polarAreaSeries.DataPoints.Add(polarPoint);

polarPoint = new PolarDataPoint();
polarPoint.Value = 110;
polarPoint.Angle = 300;
polarAreaSeries.DataPoints.Add(polarPoint);

this.chart1.Series.Add(polarAreaSeries);
