ASP.NET 4.0中的图表控件#

我对ASP.NET 4.0中图表控件的此图表存在编程问题

我无法在SerieChartType快速行中显示值

我在脚本中添加了：

Chart1.Series["Price"].IsValueShownAsLabel = true;

但是没有显示这些值

我错过了什么

这个代码怎么了

先谢谢你

下面是我的代码

        Chart1.Series.Add("Price");
        Chart1.Series["Price"].YValueMembers = "Price";
        Chart1.Series["Price"].ChartType = SeriesChartType.FastLine;
        Chart1.Series["Price"]["LabelStyle"] = "Center";
        Chart1.Series["Price"]["PointWidth"] = "0.85";
        Chart1.Series["Price"].IsValueShownAsLabel = true;
        Chart1.Series["Price"].Font = new System.Drawing.Font("Verdana", 9, FontStyle.Bold);
        Chart1.Series["Price"].LabelForeColor = System.Drawing.Color.FromArgb(0, 0, 128);
        Chart1.Series["Price"]["LabelStyle"] = "Top";
        Chart1.Series["Price"].Color = System.Drawing.Color.FromArgb(153, 153, 255);
        Chart1.Series["Price"]["PixelPointDepth"] = "1.0";
        Chart1.Series["Price"]["DrawingStyle"] = "Cylinder";
        Chart1.Series["Price"].BorderWidth = 3;
        Chart1.Series["Price"].MarkerColor = Color.Red;
