silverlight中折线图不显示，柱形图和柄形图显示都没有问题。请各位看看，可以通过QQ发源代码 QQ:690310112
下面是web service代码



//获得项目每天产出人天

        [WebMethod]

        public List<ProjectRenTian> GetProjectRenTian()

        {

            List<ProjectRenTian> reProjectRenTian = new List<ProjectRenTian>();

            OleDbCommand com = new OleDbCommand();

            //SQLExcute("Select 项目名称,完成时间,sum(折合人天) from BaseData group by 项目名称,完成时间 order by 项目名称,完成时间", com);

            SQLExcute("Select 完成时间,sum(折合人天) from BaseData1 group by 完成时间 order by 完成时间", com);

            OleDbDataAdapter ProRenTianAdp = new OleDbDataAdapter();

            ProRenTianAdp.SelectCommand = com;

            DataSet ds = new DataSet();

            ProRenTianAdp.Fill(ds);

            foreach (DataRow dr in ds.Tables[0].Rows)

            {

                ProjectRenTian rt = new ProjectRenTian();

                //rt.ProjectName = dr[0].ToString();

                rt.Date1 = dr[0].ToString().Replace(" 0:00:00","");

               

                rt.RenTian = Convert.ToInt32(dr[1]);

                reProjectRenTian.Add(rt);

            }

            return reProjectRenTian;

        }

下面是XAML CS代码
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
ProcessDataSoapClient pclinet = new ProcessDataSoapClient();
pclinet.GetProjectRenTianCompleted += new EventHandler<GetProjectRenTianCompletedEventArgs>(pclinet_GetProjectRenTianCompleted);
pclinet.GetProjectRenTianAsync();

}

void pclinet_GetProjectRenTianCompleted(object sender, GetProjectRenTianCompletedEventArgs e)
{
ObservableCollection<ServiceReference1.ProjectRenTian> pj = e.Result;
userDataGrid.ItemsSource = e.Result;
priRenTian = e.Result.ToList<ServiceReference1.ProjectRenTian>();
loadline(priRenTian);

}
void loadline(List<ServiceReference1.ProjectRenTian> list)
{

Action<Chart> chartModifier = (chart) =>
{
Axis dateAxis = new Axis { Orientation = AxisOrientation.Horizontal, Title = "完成日期", ShowGridLines = true, Interval = 1};
chart.Axes.Add(dateAxis);
Axis valueAxis = new Axis { Orientation = AxisOrientation.Vertical, Title = "产出人天", ShowGridLines = true, ShowLabels = true };
chart.Axes.Add(valueAxis);
};
chartModifier(myLine);

LineSeries series = new LineSeries();
series.ItemsSource = list;
series.IndependentValueBinding = new System.Windows.Data.Binding("Date1");
series.DependentValueBinding = new System.Windows.Data.Binding("RenTian");

myLine.Series.Add(series);
}
