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。
