我有Win RT Xaml Toolkit的图表,我希望显示像这样的ColumnSeries:

<charting:Chart Name="columnChart" Grid.Row="1" Grid.Column="1" Width="400" Height="400">
    <charting:Chart.Series>
        <charting:ColumnSeries  
             ItemsSource="{Binding items}"
             IndependentValueBinding="{Binding Name}"
             DependentValueBinding="{Binding Value}" 
             IsSelectionEnabled="True">
        </charting:ColumnSeries>  
    </charting:Chart.Series>
</charting:Chart>

但我总是收到此错误:

  

WinRT信息:无法添加类型实例   'WinRTXamlToolkit.Controls.DataVisualization.Charting.ColumnSeries'到'   一个类型的集合   'System.Collections.ObjectModel.Collection&LT; WinRTXamlToolkit.Controls.DataVisualization.Charting.ISeries&GT;'

这可能是什么原因?

好的,我找到了,

错误是 ColumnSeries 缺少标题属性,如下所示:

<charting:Chart Name="columnChart" Grid.Row="1" Grid.Column="1" Width="400" Height="400">
    <charting:Chart.Series>
        <charting:ColumnSeries  
             Title="Chart Title"
             ItemsSource="{Binding items}"
             IndependentValueBinding="{Binding Name}"
             DependentValueBinding="{Binding Value}" 
             IsSelectionEnabled="True">
        </charting:ColumnSeries>  
    </charting:Chart.Series>
</charting:Chart>

似乎标题属性是强制性的。
