有没有办法在WP7中绘制饼图？
如果没有，有没有办法绘制一个椭圆，其中有一个基于用户值的扇区？
我已经看过一些第三方工具来绘制饼图，但我不满意......
请提供任何代码或任何其他方式来获取饼图
我尝试了以下操作，但它不起作用：
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，您可以使用它来绘制带有两个分区的饼图.....在Windows Phone 7中使用xaml代码........
