Namespace: DevExpress.XtraCharts
Assembly: DevExpress.XtraCharts.v24.2.dll
Declaration
[XtraChartsLocalizableCategory(XtraChartsCategory.Behavior)]
public bool ShowLevel76_4 { get; set; }Property Value

|---|---|
| Boolean | true if the level of 76.4% should be displayed; otherwise, false. |
Remarks
Using of the ShowLevel76_4 property may be helpful for trend analysis.
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.
using System;
using System.Drawing;
using System.Windows.Forms;
using DevExpress.XtraCharts;
namespace FibonacciIndicators {
public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
#region Initialization
private void Form1_Load(object sender, EventArgs e) {
// Create a series.
Series series = new Series("Stock", ViewType.Stock);
series.ArgumentScaleType = ScaleType.DateTime;
// Populate the series with data.
AddPoints(series);
// Add it to the chart.
this.chartControl1.Series.Add(series);
// Adjust the chart's appearance.
XYDiagram diagram = (XYDiagram)this.chartControl1.Diagram;
diagram.AxisY.WholeRange.AlwaysShowZeroLevel = false;
diagram.AxisX.Label.Staggered = true;
