Assembly: DevExpress.Xpf.Charts.v22.2.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

public class BoxPlotSeries2D :
    XYSeries2D,
    ISideBySideBarSeriesView,
    IBarSeriesView,
    IGeometryHolder,
    ILineSeries

Remarks

The following image shows a Box Plot chart and its elements:

To create a Box Plot point, you should specify the following parameters:

  • Min
  • Max
  • First Quartile
  • Third Quartile
  • Median

The following parameters are optional:

  • Mean
  • Outliers

You can manually add points to a series or generate points from a data source. Refer to the Providing Data section for more about different approaches on how to populate a series with points.

The BoxPlotSeries2D class introduces the options that allow you to customize the appearance of Box Plot chart elements:

To change series point animation-related settings, use the PointAnimation property.

Example

This example shows how to create a Box Plot chart:

  1. Create a ChartControl and specify its ChartControl.Diagram property to a 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.

  2. Add a BoxPlotSeries2D 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.

  3. Use the following properties to bind the series to data:

  4. The following properties allow you to customize the Box Plot chart appearance:
