造型Wpf饼图

Question

这是饼图的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>

以下是填写数据的代码

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;
}

输出如下

现在我如何更改图表各个部分的背景颜色。类似于下面的图表。

我认为您应该可以使用Color Palette。请查看StackOverflow上的How to set a default colour to the Pie slices in WPF Pie chart帖子。

此外，请查看MSDN上的Chart Appearance文章。
