How to: Create a 2D Step Area Chart

The following example demonstrates how to create a Step Area chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add an AreaStepSeries2D object with points to the diagram's Diagram.Series collection.

Also, this example shows how to add a chart title.
