FibonacciIndicator.ShowLevel0 Property
Gets or sets the value which determines whether to display the 0% level for the Fans type of Fibonacci Indicators.
Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v23.2.dll
NuGet Package: DevExpress.Charts
Declaration
[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
public bool ShowLevel0 { get; set; }Property Value
| Type | Description |
|---|---|
| Boolean | true if the 0% level should be displayed; otherwise, false. |
Remarks
Use the ShowLevel0 property to display the 0% level within the Fans type of Fibonacci Indicators. This may be helpful for trend analysis.
Note
This property is in effect for Fibonacci Fans only, because the 0% level isn’t available for Fibonacci Arcs, and is displayed permanently for Fibonacci Retracement.
Note that it is possible to customize the visual properties of the line representing this level in a chart, by setting the FibonacciIndicator.BaseLevelColor and FibonacciIndicator.BaseLevelLineStyle properties. The label options of this level can also be customized by using the FibonacciIndicatorLabel.BaseLevelTextColor property.
Example
This example demonstrates how to create a Fibonacci Indicator of a certain kind (Arcs, Fans or Retracements), and add it to a financial series.
To do this, create an instance of the FibonacciIndicator class, and specify its FibonacciIndicator.Kind property. Then, add this indicator to the series collection of indicators, returned by the XYDiagram2DSeriesViewBase.Indicators property.
