Example

This example shows how to create a waterfall chart.

• Create a ChartControl and specify its ChartControl.Diagram property to an XYDiagram2D object. Note that the ChartControl.Diagram is a content property. You can declare a diagram in XAML directly after a chart control’s declaration without wrapping it in opening and closing ChartControl.Diagram tags.

• Add a WaterfallSeries2D object to the Diagram.Series collection. Note that the Diagram.Series is a content property. You can declare series in XAML directly after a diagram’s declaration without wrapping them in opening and closing Diagram.Series tags.

• Use the following properties to bind the series to data:

  • Series.DataSource - Specifies the series’s data source.
  • Series.ArgumentDataMember - Defines the data member that provides the series’s arguments.
  • Series.ValueDataMember - Specifies the data member that provides the series’s values.

• Use the WaterfallSeries2D.ValueOptions property to set value options. If data source stores value differences, use the WaterfallRelativeValueOptions. Use the WaterfallAbsoluteValueOptions class if the data source stores absolute data values.
