StackedBarSeriesView() Constructor

Initializes a new instance of the StackedBarSeriesView class with the default settings.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v23.2.dll

NuGet Package: DevExpress.Charts

Declaration

C#

public StackedBarSeriesView()

VB.NET

Public Sub New

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.
