PieSeries饼图怎么绑定数据？

DDRsun3 2013-05-23 11:55:04



 <toolkit:Chart Name="cr_ProductShow" Title="市场占有率">

            <toolkit:Chart.Series>

                <toolkit:PieSeries DependentValueBinding="{Binding }" IndependentValueBinding="{Binding }"/>

            </toolkit:Chart.Series>

        </toolkit:Chart>

数据绑定



 private void Chartcontrol_Loaded(object o, RoutedEventArgs e)

        {

            List<KeyValuePair<string, int>> Companys = new List<KeyValuePair<string, int>>();

            Companys.Add(new KeyValuePair<string, int>("宝锶", 1000));

            Companys.Add(new KeyValuePair<string, int>("华为", 200));

            Companys.Add(new KeyValuePair<string, int>("三星", 600));

            Companys.Add(new KeyValuePair<string, int>("Apple", 100));

            Companys.Add(new KeyValuePair<string, int>("Nokia", 50));

            Companys.Add(new KeyValuePair<string, int>("HTC", 300));

 

            ((System.Windows.Controls.DataVisualization.Charting.PieSeries)cr_ProductShow.Series[0]).ItemsSource = Companys;     

        }

为什么右边那里有数据显示，但是饼图呢？是不是好要用个什么属性来显示？

还有个请况就是：
我改成
DependentValueBinding="{Binding Key}" IndependentValueBinding="{Binding Value}"
的时候，运行空白，页面全空白，什么情况？
谢谢啦
