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

    It uses WriteableBitmap for rendering; Its advantage is that it will render the series with large quantity of data in a fraction of milliseconds.

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