Wpf中带标签的柱系列图

Question

我System.Windows.Controls.DataVisualization.Toolkit.dll用来为我的基于C#的wpf应用程序生成图表.这是我的图表的xaml.

<chartingToolkit:Chart  Name="chartDailySales"   
  Title="Monthly Sales" 
  VerticalAlignment="Top" Margin="10,10,0,0" 
  Height="262" 
  BorderBrush="#00000000" 
  DataContext="{Binding}" 
  IsTabStop="True"
  Background="#ffbcd5c7">

       <!-- Plot area-->
       <chartingToolkit:Chart.PlotAreaStyle>
           <Style TargetType="Grid">
               <Setter Property="Background" Value="White" />
           </Style>
       </chartingToolkit:Chart.PlotAreaStyle>



           <!-- Hide Legend-->
       <chartingToolkit:Chart.LegendStyle>
           <Style TargetType="Control">
               <Setter Property="Width" Value="0"/>
               <Setter Property="Height" Value="0"/>
           </Style>
       </chartingToolkit:Chart.LegendStyle>



       <chartingToolkit:ColumnSeries DependentValuePath="Value" 
        IndependentValuePath="Key" 
        ItemsSource="{Binding}" 
        IsSelectionEnabled="False"
        >


           <chartingToolkit:ColumnSeries.DataPointStyle>
               <Style TargetType="chartingToolkit:ColumnDataPoint">
                   <Setter Property="Background" Value="#ff217346"/>
                   <Setter Property="BorderBrush" Value="#ff217346" />
                   <Setter Property="BorderThickness" Value="1" />

               </Style>

           </chartingToolkit:ColumnSeries.DataPointStyle>

       </chartingToolkit:ColumnSeries>
   </chartingToolkit:Chart>

这是填充数据的代码.

List<KeyValuePair<string, double>> monthlySalesList = new List<KeyValuePair<string, double>>();
        monthlySalesList.Add(new KeyValuePair<string, double>("JAN", 1234 ));
        monthlySalesList.Add(new KeyValuePair<string, double>("FEB", 2204));
        monthlySalesList.Add(new KeyValuePair<string, double>("MAR", 3234));
        monthlySalesList.Add(new KeyValuePair<string, double>("APR", 3234));
        monthlySalesList.Add(new KeyValuePair<string, double>("MAY", 5234));
        monthlySalesList.Add(new KeyValuePair<string, double>("JUN", 6234));
        monthlySalesList.Add(new KeyValuePair<string, double>("JUL", 8234));
        monthlySalesList.Add(new KeyValuePair<string, double>("AUG", 6234));
        monthlySalesList.Add(new KeyValuePair<string, double>("SEP", 7234));
        monthlySalesList.Add(new KeyValuePair<string, double>("OCT", 9234));
        monthlySalesList.Add(new KeyValuePair<string, double>("NOV", 11234));
        monthlySalesList.Add(new KeyValuePair<string, double>("DEC", 10234));

        chartDailySales.DataContext = monthlySalesList;

这是输出.

现在如何标记图表如下.

谢谢.

为什么不更改 DataPointStyle 中 ColumnDataPoint 的模板，类似于 此处
