How to: Create a 2D Overlapped Range Bar Chart
The following example demonstrates how to create a 2D Overlapped Range Bar chart. To do this, it is necessary to assign the ChartControl.Diagram property to XYDiagram2D, and then add two RangeBarOverlappedSeries2D objects with points to the diagram's Diagram.Series collection.
Also, this example shows how to add a chart title and to hide markers and labels for both series to improve chart appearance.
