Syntax
public class FastRangeAreaBitmapSeries : RangeSeriesBase, ICloneable, ISupportAxes2D, ISupportAxes, ISegmentSelectable
Remarks

Examples
      <syncfusion:FastRangeAreaBitmapSeries ItemsSource="{Binding Data}" XBindingPath="Year" High="High" Low="Low">
      </syncfusion:FastRangeAreaBitmapSeries>
      FastRangeAreaBitmapSeries series1 = new FastRangeAreaBitmapSeries();
      series1.ItemsSource = viewmodel.Data;
      series1.XBindingPath = "Year";
      series1.Low = "Low";
      series1.High="High";
      chart.Series.Add(series1);
