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.v25.2.dll

NuGet Package : DevExpress.Charts

Declaration

csharp
[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
public bool ShowLevel0 { get; set; }
vb
<XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)>
Public Property ShowLevel0 As Boolean

Property Value

TypeDescription
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.
