StackedBarSeriesView Class

Represents a series view of the Stacked Bar type.

Assembly: DevExpress.XtraCharts.v23.2.dll

Declaration

C#
VB.NET

public class StackedBarSeriesView :
    BarSeriesView,
    IStackedView

Public Class StackedBarSeriesView
    Inherits BarSeriesView
    Implements IStackedView

Remarks

The StackedBarSeriesView class provides the functionality of a series view of the stacked bar type within a chart control. At the same time, the StackedBarSeriesView class serves as a base for the FullStackedBarSeriesView class.

The StackedBarSeriesView class inherits properties and methods from the base BarSeriesView class which define the common settings of bar series views.

Note that a particular view type can be defined for a series via its SeriesBase.View property.

For more information on series views of the stacked bar type please see the Stacked Bar Chart topic.

Example

This example shows how to bind a chart control to a data source and create two Stacked Bar series based on a series template.

Stacked bar chart

Add a chart to the WinForms project and specify the chart’s data source.
Use the ChartControl.SeriesTemplate property to access and configure series template options:
- Call the ChangeView(ViewType) method to specify the view type of generated series.
- Specify the SeriesDataMember property to define a data member that stores names for generated series.
- Call the SetDataMembers(String, String) method to define data members that store point arguments and values.
Define the BarWidth property to specify the width of stacked bars in x-axis units.
Use the x-axis’ Tickmarks property to access and configure tickmark settings. This example shows how to disable x-axis minor tickmarks.
Add a title on the chart.
Customize the chart legend. This example enables legend check boxes to allow users to hide and show series, and specifies the legend position.
