WinRT Xaml图表中的区间与UWP

Question

这个问题并不新鲜：带有LinearAxis的图表只使用整数。很多答案都建议使用Interval，但如果我有最小值= 1和最大值= 100，Interval = 1，轴将有100个数字，数量太多。我想要的是对LinearAxis的自动间隔计算进行一些修改。因此，这里的解决方案发现Andrew Barrett：

后，我申请我的示例应用程序与他的代码：

class Report 
{ 
    public string months { get; set; } 
    public int countlent { get; set; } 
} 

public MainPage() 
{ 
    this.InitializeComponent(); 
    LoadChartContents(); 
} 

private void LoadChartContents() 
{ 
    List<Report> lstSource = new List<Report>(); 
    lstSource.Add(new Report() { months = "1", countlent = 10 }); 
    lstSource.Add(new Report() { months = "2", countlent = 15 }); 
    lstSource.Add(new Report() { months = "3", countlent = 20 }); 
    lstSource.Add(new Report() { months = "4", countlent = 10 }); 
    lstSource.Add(new Report() { months = "5", countlent = 13 }); 
    lstSource.Add(new Report() { months = "6", countlent = 18 }); 
    lstSource.Add(new Report() { months = "7", countlent = 33 }); 
    lstSource.Add(new Report() { months = "8", countlent = 41 }); 
    lstSource.Add(new Report() { months = "9", countlent = 31 }); 
    lstSource.Add(new Report() { months = "10", countlent = 21 }); 
    lstSource.Add(new Report() { months = "11", countlent = 12 }); 
    lstSource.Add(new Report() { months = "12", countlent = 37 }); 
    (LineChart.Series[0] as LineSeries).DependentRangeAxis = new LineSeriesAxis(); 
    (LineChart.Series[0] as LineSeries).ItemsSource = lstSource; 
} 

的XAML页面：

<Chart:Chart x:Name="LineChart" HorizontalAlignment="Center" Margin="5" Width="500"> 
    <Chart:LineSeries Title="Chart Name" IndependentValuePath="months" DependentValuePath="countlent" /> 
</Chart:Chart> 

每次我运行或调试应用程序它停止并显示App.gics页面

#if DEBUG && !DISABLE_XAML_GENERATED_BREAK_ON_UNHANDLED_EXCEPTION 
     UnhandledException += (sender, e) => 
     { 
      if (global::System.Diagnostics.Debugger.IsAttached) global::System.Diagnostics.Debugger.Break(); 
     }; 
#endif 

我在用他的代码吗？我正在使用UWP和WinRTXamlToolkit.Controls.DataVisualization.Charting Toolkit。

您在代码隐藏中分配轴的方式有点“有风险”。试试这个：

XAML：

<Charting:Chart x:Name="LineChart" HorizontalAlignment="Center" Margin="5" Width="500"> 
     <Charting:Chart.Axes> 
      <local:LineSeriesAxis Orientation="Y"></local:LineSeriesAxis> 
     </Charting:Chart.Axes> 
     <Charting:LineSeries Title="Chart Name" 
          IndependentValuePath="months" 
          DependentValuePath="countlent" 
          ItemsSource="{Binding}" /> 
    </Charting:Chart> 

CS：

private void LoadChartContents() 
    { 
     List<Report> lstSource = new List<Report>(); 
     lstSource.Add(new Report() { months = "1", countlent = 10 }); 
     lstSource.Add(new Report() { months = "2", countlent = 15 }); 
     lstSource.Add(new Report() { months = "3", countlent = 20 }); 
     lstSource.Add(new Report() { months = "4", countlent = 10 }); 
     lstSource.Add(new Report() { months = "5", countlent = 13 }); 
     lstSource.Add(new Report() { months = "6", countlent = 18 }); 
     lstSource.Add(new Report() { months = "7", countlent = 33 }); 
     lstSource.Add(new Report() { months = "8", countlent = 41 }); 
     lstSource.Add(new Report() { months = "9", countlent = 31 }); 
     lstSource.Add(new Report() { months = "10", countlent = 21 }); 
     lstSource.Add(new Report() { months = "11", countlent = 12 }); 
     lstSource.Add(new Report() { months = "12", countlent = 37 }); 

     DataContext = lstSource; 
    }
