StockSeriesView Class
Represents a series view of the Stock type.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v20.1.dll
NuGet Packages: DevExpress.Charts, DevExpress.WindowsDesktop.Charts
Declaration
Remarks
The StockSeriesView class provides the functionality of a series view of the stock type within a chart control.
In addition to the common financial view settings inherited from the base FinancialSeriesViewBase class, the StockSeriesView class declares a stock type specific setting that allows you to control which open-close level lines should be displayed within the view (StockSeriesView.ShowOpenClose).
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 stock bar type please see the Stock Chart topic.
Example
This example creates a ChartControl with a series of the StockSeriesView type and adds this chart to a form at runtime. Before you proceed with this example, create a Windows Forms Application in Visual Studio and include all necessary assemblies in the References list of your project.
