Question

我试图将氧气图包含在Xamarin.Forms-Project

中

这是我的Xaml.cs文件，我正在构建PlotModel。

private void GeneratePlot()
    {
        var Points = new List<DataPoint>
        {
            new DataPoint(0, 0),
            new DataPoint(10, 5),
            new DataPoint(20, 10),
            new DataPoint(30, 16),
            new DataPoint(40, 12),
            new DataPoint(50, 19)
        };
        var Points2 = new List<DataPoint>
        {
            new DataPoint(0, 0),
            new DataPoint(10, 7),
            new DataPoint(20, 8),
            new DataPoint(30, 8),
            new DataPoint(40, 20),
            new DataPoint(50, 25)
        };
        var m = new PlotModel();
        m.PlotType = PlotType.XY;
        m.InvalidatePlot(true);
        m.Title = "hello oxy";
        m.ResetAllAxes();
        var ls1 = new LineSeries();
        var ls2 = new LineSeries();
        ls1.ItemsSource = Points;
        ls2.ItemsSource = Points2;

        m.Series.Add(ls1);
        m.Series.Add(ls2);
        var _opv = new OxyPlotView
        {
            WidthRequest = 300,
            HeightRequest = 300,
            BackgroundColor = Color.Aqua
        };
        _opv.Model = m;
        PlModel = m;
    }

在Code中，只需将OxyPlotModel _opy放入StackLayout即可。但是当我要像这样将它添加到Xaml中时：

 <oxy:PlotView Model="{Binding Model}" VerticalOptions="Center" HorizontalOptions="Center" />

我得到以下例外：

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: An exception was thrown by the type initializer for OxyPlot.XamarinForms.PlotView ---> System.MissingMethodException: Method not found: 'Xamarin.Forms.BindableProperty.Create'.

有谁知道我可以做些什么来使用Xaml的OxyPlot？

非常感谢

确保您拥有的OxyPlot版本与您拥有的表格版本兼容。

我不得不手动下载OxyPlot源并在过去更新Xamarin.Forms NuGet。
