VS2010中 chart图表显示为红叉,急急急!!!
本帖最后由 czc411 于 2011-11-23 17:02:36 编辑 最近在研究chart,在VS2010,4.0,将微软提供的示例在工程中执行,显示的是红叉,为什么???

在工程的根目录下可以显示,在子目录下显示红叉,是哪里配置问题?

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));
Chart1.Titles.Add(t);
Chart1.ChartAreas.Add("Series 1");
// create a couple of series
Chart1.Series.Add("Series 1");
Chart1.Series.Add("Series 2");




// add points to series 1
Chart1.Series["Series 1"].Points.AddY(5);
Chart1.Series["Series 1"].Points.AddY(8);

<p class="dscr">It is recommended that you use code-behind for your ASP.NET pages
when using the Chart control. This separates the user interface and its logic.</p>

"..\\TempImages\\ChartPic_#SEQ(200,30)";

修改一下这里,在根目录里,这里向上线目录也仍是根目录,在子目录后,向一级就到其他目录了。
