StackedBarSeriesView Class
Represents a series view of the Stacked Bar type.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v24.1.dll
NuGet Package: DevExpress.Charts
Declaration
[TypeConverter(typeof(StackedBarSeriesViewTypeConverter))]
public class StackedBarSeriesView :
BarSeriesView,
IStackedViewRemarks
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.
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.

// Enable series point labels, specify their text pattern and position:
chart.SeriesTemplate.LabelsVisibility = DevExpress.Utils.DefaultBoolean.True;
chart.SeriesTemplate.Label.TextPattern = "${V}M";
((BarSeriesLabel)chart.SeriesTemplate.Label).Position = BarSeriesLabelPosition.Center;
// Customize series view settings (for example, bar width):
StackedBarSeriesView view = (StackedBarSeriesView)chart.SeriesTemplate.View;
view.BarWidth = 0.8;
// Disable minor tickmarks on the x-axis:
XYDiagram diagram = (XYDiagram)chart.Diagram;
diagram.AxisX.Tickmarks.MinorVisible = false;
// Add a chart title:
chart.Titles.Add(new ChartTitle { Text = "Sales by Products" });
// Specify legend settings:
chart.Legend.MarkerMode = LegendMarkerMode.CheckBoxAndMarker;
chart.Legend.AlignmentHorizontal = LegendAlignmentHorizontal.Center;
chart.Legend.AlignmentVertical = LegendAlignmentVertical.TopOutside;
