微软去年１１月发布了一个很酷的新ASP.NET服务器控件,<asp:chart />,可以免费用在ASP.NET 3.5中，而且还可以用在asp.net mvc。可以看新ASP.NET图表控件<asp:chart runat="server"/>。

ASP.NET图表控件
我今天才知道ASP.NET图表控件发布了，附一个在线文档
在这里有一篇文章简短介绍了Combining ASP.NET MVC and ASP.NET Charting Controls．
编辑Web.Config
将控件的命名空间加到 (path: "<system.web><pages><controls>") :
<add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
添加一个 httpHandler ("<httpHandlers>"下面) :
<add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>
将chart 控件添加到view
<p> <% System.Web.UI.DataVisualization.Charting.Chart Chart2 = new System.Web.UI.DataVisualization.Charting.Chart(); Chart2.Width = 412; Chart2.Height = 296; Chart2.RenderType = RenderType.ImageTag; Chart2.Palette = ChartColorPalette.BrightPastel; Title t = new Title("No Code Behind Page", Docking.Top, new System.Drawing.Font("Trebuchet MS", 14, System.Drawing.FontStyle.Bold), System.Drawing.Color.FromArgb(26, 59, 105)); Chart2.Titles.Add(t); Chart2.ChartAreas.Add("Series 1"); // create a couple of series Chart2.Series.Add("Series 1"); Chart2.Series.Add("Series 2"); // add points to series 1 foreach (int value in (List<int>)ViewData["Chart"]) { Chart2.Series["Series 1"].Points.AddY(value); } // add points to series 2 foreach (int value in (List<int>)ViewData["Chart"]) { Chart2.Series["Series 2"].Points.AddY(value + 1); } Chart2.BorderSkin.SkinStyle = BorderSkinStyle.Emboss; Chart2.BorderColor = System.Drawing.Color.FromArgb(26, 59, 105); Chart2.BorderlineDashStyle = ChartDashStyle.Solid; Chart2.BorderWidth = 2; Chart2.Legends.Add("Legend1"); // Render chart control Chart2.Page = this; HtmlTextWriter writer = new HtmlTextWriter(Page.Response.Output); Chart2.RenderControl(writer); %> </p>
效果如下：
