如何更改 WinRT XAML Toolkit 图表控件中图表控件的调色板颜色？

例如，我想更改饼图切片的颜色。

如果您在工具包的源代码中搜索“Palette”，您将看到 Chart 控件的默认样式如何具有 Palette 属性，该属性是 ResourceDictionary 的集合>。您可以在您的应用中以类似的方式将其作为图表 Style 或直接作为其属性应用，例如

<charting:Chart
    x:Name="PieChartWithCustomPalette"
    Title="Pie Chart with Custom Palette"
    Margin="70,0">
    <charting:Chart.Palette>
        <charting:ResourceDictionaryCollection>
            <!-- Blue -->
            <ResourceDictionary>
                <SolidColorBrush
                    x:Key="Background"
                    Color="#4586d8" />
                <Style
                    x:Key="DataPointStyle"
                    TargetType="Control">
                    <Setter
                        Property="Background"
                        Value="{StaticResource Background}" />
                </Style>
                <Style
                    x:Key="DataShapeStyle"
                    TargetType="Shape">
                    <Setter
                        Property="Stroke"
                        Value="{StaticResource Background}" />
                    <Setter
                        Property="StrokeThickness"
                        Value="2" />
                    <Setter
                        Property="StrokeMiterLimit"
                        Value="1" />
                    <Setter
                        Property="Fill"
                        Value="{StaticResource Background}" />
                </Style>
            </ResourceDictionary>
            <!-- Red -->
            <ResourceDictionary>
                <SolidColorBrush
                    x:Key="Background"
                    Color="#dc443f" />
                <Style
                    x:Key="DataPointStyle"
                    TargetType="Control">
                    <Setter
                        Property="Background"
                        Value="{StaticResource Background}" />
                </Style>
                <Style
                    x:Key="DataShapeStyle"
                    TargetType="Shape">
                    <Setter
                        Property="Stroke"
                        Value="{StaticResource Background}" />
                    <Setter
                        Property="StrokeThickness"
                        Value="2" />
                    <Setter
                        Property="StrokeMiterLimit"
                        Value="1" />
                    <Setter
                        Property="Fill"
                        Value="{StaticResource Background}" />
                </Style>
            </ResourceDictionary>
        </charting:ResourceDictionaryCollection>
    </charting:Chart.Palette>
    <charting:Chart.Series>
        <Series:PieSeries
            Title="Population"
            ItemsSource="{Binding Items}"
            IndependentValueBinding="{Binding Name}"
            DependentValueBinding="{Binding Value}"
            IsSelectionEnabled="True" />
    </charting:Chart.Series>
</charting:Chart>

我将此添加到示例项目中以供将来引用。
