Library	Related API Members
Cross-Platform Class Library	ReductionStockOptions.Level
	StockPointOptions.ValueLevel

Remarks

The values listed by the StockLevel enumeration are used to set the ReductionStockOptions.Level and StockPointOptions.ValueLevel properties.

Example

This example demonstrates how to create a ChartControl with a series of the StockSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary 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 AxisBase.WorkdaysOnly and AxisBase.WorkdaysOptions properties. And, to learn which instruments for financial analysis are available in XtraCharts, refer to Indicators.
