RadHtmlChart不显示来自数据源的数据

这是一个我想要展示的简单条形图。

这是我的图表:

 <telerik:RadHtmlChart runat="server" ID="Chart_WarrantiesByMonth" Width="800" Height="500" Transitions="true">
                    <Appearance>
                        <FillStyle BackgroundColor="White"></FillStyle>
                    </Appearance>
                    <ChartTitle Text="Warranties By Month">
                    </ChartTitle>
                </telerik:RadHtmlChart>

这是我的数据绑定调用

DataTable chartSource = new DataTable();
        MySqlCommand mysqlcmdChart = new MySqlCommand();
        mysqlcmdChart.CommandText = "_DealerPortal_Chart_WarrantiesByMonth";
        mysqlcmdChart.Parameters.AddWithValue("DealershipIdParam", DealershipIdParam);
        chartSource = MySQLProcessing.MySQLProcessor.DataTable_StoredProcedure(mysqlcmdChart,mysqlCon,CommandType.StoredProcedure);

        Chart_WarrantiesByMonth.DataSource = chartSource;
        Chart_WarrantiesByMonth.PlotArea.XAxis.DataLabelsField = "Date";
        Chart_WarrantiesByMonth.PlotArea.XAxis.Name = "Date";
        Chart_WarrantiesByMonth.PlotArea.YAxis.Name = "Warranties";
        Chart_WarrantiesByMonth.DataBind();

我确保我的图表有数据;

Warranties  Date
1   August 2014
13  December 2013
40  February 2014
8   January 2014
13  March 2014
1   May 2015

这真令人沮丧,我会让我尖叫。无论我做什么,我都无法让图表显示除此之外的任何内容:有一件事是我在按钮上执行一个简单的asp按钮来执行数据绑定。我期待我的x轴是月/年,y是计数。谢谢!

谢谢!

我认为你需要定义一个系列:http://demos.telerik.com/aspnet-ajax/htmlchart/examples/functionality/dateaxis/defaultcs.aspx。否则,图表应显示哪些数据?从它的外观来看,你需要一个LineSeries(就像那个演示一样),它的DataFieldY属性应该设置为&#34; Warranties&#34;
