Inherited Members
Namespace: Syncfusion.SfChart.XForms
Assembly: Syncfusion.SfChart.XForms.dll
Syntax
public class BollingerBandIndicator : FinancialTechnicalIndicator, IThemeElement
Remarks

This indicator can be associated to a financial series in SfChart by specifying the name of series using SeriesName property. If the SeriesName is specified, all the required properties such as ItemsSource, XBindingPath, High, Low, Open and Close will be derived from the associated series. In case, the SeriesName is not specified, all those required properties need to be explicitly specified in BollingerBandIndicator.

Examples
SfChart chart = new SfChart();
chart.PrimaryAxis = new NumericalAxis();
chart.SecondaryAxis = new NumericalAxis();
CandleSeries series = new CandleSeries();
series.Name = "series";
ObservableCollection Data = new ObservableCollection
{
  new ChartDataPoint(1, 30,35,20,25),
  new ChartDataPoint(2, 90,100,10,20),
  new ChartDataPoint(3, 20,90,10,80),
  new ChartDataPoint(5, 10,0,80,70),
  new ChartDataPoint(10, 25,20,49,12),
  new ChartDataPoint(12, 68,60,30,50)
};
series.ItemsSource = Data;
chart.Series.Add(series);
chart.TechnicalIndicators.Add(new BollingerBandIndicator(){SeriesName="series"});
