WP7中的饼图

Question

有没有什么办法来绘制饼图WP7？

如果没有，有没有办法绘制一个具有基于用户价值的扇形的椭圆？

我已经看到了一些第三方工具来绘制饼图，但是对此我并不满意。

请提供任何代码或任何其他方式来获取饼图

我曾尝试以下，但它不工作：

        EllipseGeometry OuterEllipse = new EllipseGeometry();
        EllipseGeometry InnerEllipse = new EllipseGeometry();
        OuterEllipse.Center = new Point(100, 100);
        OuterEllipse.RadiusX = 100;
        OuterEllipse.RadiusY = 100;

        InnerEllipse.Center = new Point(100, 100);
        InnerEllipse.RadiusX = 90;
        InnerEllipse.RadiusY = 90;

        System.Windows.Shapes.Path path = new System.Windows.Shapes.Path();
        System.Windows.Shapes.Path path1 = new System.Windows.Shapes.Path();

        SolidColorBrush solidbrush = new SolidColorBrush(Colors.Blue);
        path.Fill = solidbrush;
        path.Data = OuterEllipse;

        SolidColorBrush solidbrush1 = new SolidColorBrush(Colors.Yellow);
        path1.Fill = solidbrush1;
        path1.Data = InnerEllipse;

        Chart_stackPanel.Children.Add(path);
        Chart_stackPanel.Children.Add(path1);`

任何帮助！

这是一个示例，您可以使用xaml代码在Windows Phone7中绘制带有两个分区的饼图。
