CandleStickSeriesView Class
Represents a series view of the Candle Stick type.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v19.2.dll
Declaration
Remarks
The CandleStickSeriesView class provides the functionality of a series view of the candle stick type within a chart control.
The CandleStickSeriesView class inherits properties and methods from the base FinancialSeriesViewBase class which defines the common settings of financial 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 candle stick type please see the Candle Stick Chart topic.
Example
This example demonstrates how to create a ChartControl with a series of the CandleStickSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, create a Windows Forms Application in Visual Studio, and add all required assemblies to the References list of your project.
Then, add the following code to the Form.Load event handler.
Note that you can exclude non-working days (weekends and holidays) from an axis range via the DateTimeScaleOptions.WorkdaysOnly and DateTimeScaleOptions.WorkdaysOptions properties. Refer to Indicators for information on the financial indicators available for XtraCharts.
