A Polar Area chart displays a filled closed contour in a 2dimensional polar coordinate system. The contour is defined by a sequence of data points, where the position of each data point is specified by its distance from the center and its angle of rotation. The following image shows a polar area chart:
Polar Area series are represented by the NPolarAreaSeries type. An instance of this type must be added to the series collection of a Polar chart:
C# 
Copy Code


NPolarAreaSeries polarArea = new NPolarAreaSeries(); polarChart.Series.Add(polarArea); 
Polar Area series accept data points of type NPolarAreaDataPoint. The following code snippet shows how to add data to a polar area series:
C# 
Copy Code


NPolarAreaDataPoint polarAreaDataPoint = new NPolarAreaDataPoint(); polarAreaDataPoint.X = 10; polarAreaDataPoint.Y = 10; polarArea.DataPoints.Add(polarAreaDataPoint);
