如何重置缩放 oxyplot c# wpf

Question

我有一个 oxyplot RectangleBarSeries 和一个按钮 "Reset"。当我按下按钮时，我希望重置缩放（与按下键盘上的 A 时缩放重置的方式相同）。

我试图通过在 MainPanel.xaml.cs:

中添加一个带有以下代码的事件处理程序来实现这一点

private void Reset_Click(object sender, RoutedEventArgs e)
    {
       histogram.PlotModel.Axes[0].Reset();
       histogram.PlotModel.Axes[1].Reset(); 
    }

但出现错误 "myNameSpace.Histogram does not contain a definition for PlotModel and no extension method "PlotModel" accepting a first argument of type myNameSpace.Histogram could be found"。

我应该写什么来重置绘图的缩放？

我的直方图的一部分 class:

namespace myNameSpace
{
    public class Histogram : INotifyPropertyChanged
    {
    public Collection<Item> Items { get; set; }
    private PlotModel histogramModel;
    public PlotModel HistogramModel
    {
        get { return histogramModel; }
        set { histogramModel = value; OnPropertyChanged("HistogramModel"); }
    }

    public class Item
    {
        public string Label { get; set; }
        public double Value { get; set; }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    //NotifyPropertyChangedInvocator
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(propertyName));
        }
    }

    public Histogram(List<double> frequency, List<double> axis, string VariableName)
    {
        CreateRectangleBar(frequency, axis, VariableName);
    }

尝试使用MyPlotViewName.ResetAllAxes();相反，那应该有效。
