# How to: Create a 2D Polar Area Chart

The following example demonstrates how to create a 2D Polar Area chart.

To do this, it is necessary to assign the ChartControl.Diagram property to PolarDiagram2D, and then add a PolarAreaSeries2D object with points to the polar diagram Diagram.Series collection.
