设置 Wpf 饼图样式

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>

这是填充数据的代码

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。类似于下图。

我认为你应该能够使用调色板 http://msdn.microsoft.com/en-us/library/windows/desktop/dd183459%28v=vs.85%29.aspx。看看如何为 WPF 饼图中的饼图切片设置默认颜色 https://stackoverflow.com/questions/16667136/how-to-set-a-default-color-to-the-pie-slices-in-wpf-pie-chart在 StackOverflow 上发布。

此外，请查看图表外观 http://msdn.microsoft.com/en-us/library/dd489226.aspxMSDN 上的文章。
