在 Windows Phone 8.0 和 8.0 SDK 上测试。

只需将画笔集合添加到 PieChart 结构中即可。

使用 XAML

<chart:PieChart Height="300" Width="400" TitleMemberPath="Title" ValueMemberPath="Value">
    <chart:PieChart.Brushes>
        <SolidColorBrush Color="Red"/>  <!-- color item #1 -->
        <SolidColorBrush Color="Green"/> <!-- color item #2 -->
        <SolidColorBrush Color="Blue"/> <!-- color item #3 -->
    </chart:PieChart.Brushes>                    
    <chart:PieChart.DataSource>        
        <local:PieDataCollection>
            <local:PieData Title="Democrat" Value="123"/>
            <local:PieData Title="Republic" Value="213"/>
            <local:PieData Title="independent" Value="123"/>
        </local:PieDataCollection>
    </chart:PieChart.DataSource>
</chart:PieChart>

使用C#

public void LoadColors()
{
    System.Windows.Media.SolidColorBrush red = new System.Windows.Media.SolidColorBrush();
    red.Color = Color.FromArgb(0xFF, 0xFF, 0x00, 0x00);

    System.Windows.Media.SolidColorBrush green = new System.Windows.Media.SolidColorBrush();
    green.Color = Color.FromArgb(0xFF, 0x00, 0xFF, 0x00);

    System.Windows.Media.SolidColorBrush blue = new System.Windows.Media.SolidColorBrush();
    blue.Color = Color.FromArgb(0xFF, 0x00, 0x00, 0xFF);

    this.PieChart.Brushes.Add(red);    // add red
    this.PieChart.Brushes.Add(green);  // add green
    this.PieChart.Brushes.Add(blue);   // add blue

    this.PieChart.DataSource = Data;   // set the datasource
}
