How to: Create a 2D Area Chart

The following example demonstrates how to create a 2D Area chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add two AreaSeries2D objects with points to the diagram’s Diagram.Series collection.

Also, this example shows how to add a legend (showing series names) to a chart.
