Сложенная таблица столбцов с использованием Oxyplot и Xamarin

Question

Я использовал OxyPlot в проектах Xamarin.ios и Xamarin.Android для построения диаграмм столбцов. Вот как я нарисовал диаграмму столбцов с помощью оксиплота.

Теперь мне нужна таблица столбчатых диаграмм. Я не мог найти его в документации. Возможно ли это с помощью оксиплота? Как? Любая помощь оценена ..

public class MeasurementGraph 
{ 

    public PlotModel VitalModel { get; set; } 
    public VitalGraph graph { get; set; } 

    public MeasurementGraph (VitalGraph graph) 
    { 
     this.graph = graph; 
     var model = new PlotModel { Title = "" }; 
     model.PlotAreaBorderColor = OxyColors.Transparent; 

     model.Axes.Add (GetXAxis()); 
     model.Axes.Add (GetYAxis()); 
     model.Series.Add (GetValueSeries()); 

     if (Math.Abs (graph.trendStart) > float.Epsilon && Math.Abs (graph.trendEnd) > float.Epsilon) 
      model.Series.Add (GetXtraSeries()); 
      VitalModel = model; 
     } 

    CategoryAxis GetXAxis() 
    { 
     int fontSize; 
     if (Math.Abs (graph.trendStart) > float.Epsilon) 
      fontSize = 6; 
     else 
      fontSize = 8; 
     CategoryAxis categoryAxis = new CategoryAxis() { 
      Position = AxisPosition.Bottom, 
      MinorTickSize = 0, 
      MajorTickSize = 0, 
      MajorGridlineStyle = LineStyle.None, 
      MinorGridlineStyle = LineStyle.None, 
      FontSize = fontSize, 
      IsPanEnabled = false, 
      IsZoomEnabled = false, 
     }; 

     foreach (string day in graph.dayList) 
      categoryAxis.ActualLabels.Add (day); 
     return categoryAxis; 
    } 

    LinearAxis GetYAxis() 
    { 
     List<float> valueList = graph.valueList.Select (x => float.Parse (x)).ToList(); 
     float maxValue = valueList.Max(); 

     float minValue = valueList.Max(); 


      return new LinearAxis() { 
       AxislineStyle = LineStyle.None, 
       Position = AxisPosition.Left, 
       MinorTickSize = 0, 
       MajorTickSize = 0, 
       MajorGridlineStyle = LineStyle.Solid, 
       MajorGridlineColor = OxyColor.Parse ("#f5f5f5"), 
       MinorGridlineStyle = LineStyle.None, 
       Maximum = maxValue, 
       Minimum = minValue, 
       FontSize = 8, 
       MajorStep = (maxValue - minValue)/4, 
       IsPanEnabled = false, 
       IsZoomEnabled = false 

      }; 
     } 

     ColumnSeries GetValueSeries() 
     { 
      var series = new ColumnSeries(); 
      series.ColumnWidth = 50; 
      for (int i = 0; i < graph.valueList.Count; i++) { 
       series.Items.Add (new ColumnItem { 
        Value = double.Parse (graph.valueList [i]), 
        Color = OxyColor.Parse (graph.colorList [i]) 
       }); 
      } 
      return series; 
     } 

     LineSeries GetXtraSeries() 
     { 
      var series = new LineSeries { 
       StrokeThickness = 2, 
       MarkerType = MarkerType.None, 
       MarkerSize = 4, 
       MarkerStroke = OxyColors.White, 
       MarkerStrokeThickness = 2, 
       Color = OxyColors.Blue 
      }; 
      int xStart = graph.vitalId == 20 ? 0 : -1; 
      int xEnd = graph.vitalId == 20 ? graph.valueList.Count - 1 : graph.valueList.Count; 

      series.Points.Add (new DataPoint (xStart, graph.trendStart)); 
      series.Points.Add (new DataPoint (xEnd, graph.trendEnd)); 
      return series; 
     } 
    }

Это взято из одного из их образцов:
