造型Wpf饼图

Question

这是我的饼图xaml。

<chartingToolkit:Chart Name="pieChart" Title="Top Products" Margin="10,10,0,0" Height="262" BorderBrush="#00000000" DataContext="{Binding}" IsHitTestVisible="False" IsTabStop="True" ForceCursor="True"> 
     <chartingToolkit:PieSeries DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding}" IsSelectionEnabled="True" /> 

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

而这里是代码用于填充数据

public void GenerateChart() 
{ 
    List<KeyValuePair<string, double>> valueList = new List<KeyValuePair<string, double>>(); 
    valueList.Add(new KeyValuePair<string, double>("Apple", 101)); 
    valueList.Add(new KeyValuePair<string, double>("Banana", 201)); 
    valueList.Add(new KeyValuePair<string, double>("Cake", 20)); 
    valueList.Add(new KeyValuePair<string, double>("Others", 200));  

    pieChart.Title = "Top Products"; 
    pieChart.DataContext = valueList; 
} 

并且输出是如下

现在如何变更的各部分的背景颜色图表。类似于下图。

我认为你应该能够使用Color Palette。看看StackOverflow上的How to set a default colour to the Pie slices in WPF Pie chart这篇文章。

此外，请查看MSDN上的Chart Appearance文章。
