BarSideBySideSeries2D Class
Represents the 2D Side-by-Side Bar series.
Namespace: DevExpress.Xpf.Charts
Assembly: DevExpress.Xpf.Charts.v24.1.dll
NuGet Package: DevExpress.Wpf.Charts
Declaration
public class BarSideBySideSeries2D :
BarSeries2D,
ISideBySideBarSeriesView,
IBarSeriesViewExample
This example shows how to create a 2D Side-by-Side Bar chart.
Create a ChartControl and set 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.
Specify the Diagram.SeriesItemsSource property to bind a collection of objects used to generate series.
The Diagram.SeriesItemTemplate property allows you to define a template for all series. Use the following API members to configure a series item:
Member Description BarSideBySideSeries2DRepresents the 2D Side-by-Side Bar series. 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. Series.DisplayName Gets or sets the display name of the series. For more information on how to populate a chart with data, see the following section: Providing Data
Use the following API members to configure the x-axis options.
Member Description XYDiagram2D.AxisX Gets the X-axis. AxisX2D Represents the X-axis of a XYDiagram2D class. AxisX2D.DateTimeScaleOptions Provides access to the options that define the behavior of a date-time X-scale when its mode is manual, automatic or continuous. Create a legend and customize its settings. For more information about legends, refer to the following topic: Legends
