Polar Area Series

A Polar Area chart displays a filled closed contour in a 2-dimensional 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:

Creating a Polar Area Series

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);

Passing Data

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);
