我这些代码放到一个服务器上后，就不能显示图片了，我想是因为我在服务器上没有写入的权限，所以图片不能保存到特定<br />的文件夹中，所以就显示不出来了，但是如何解决呢？？？？<br /><br />小弟急求答案！！<br /></pre>

- 检查路径下是否生成图片
- 检查Session["serisCol"]是否为空
我检查了，是有值的！ 但是就是没有生成图片！！

PIC文件夹存在不？
如果是真的没有写入权限的话，那难办了。
dotnetCHARTING是先生成临时图片到指定文件的
或者你指定下生成的图名称再试试看
chart2.DefaultSeries.DefaultElement.ToolTip = "%SeriesName"; chart2.TempDirectory = "temp";
chart2.FileName = "Group";
是在别个的服务器上的，我想就是没有写入的权限导致成的，PIC的文件夹是存在的，名称的我试过了，也没有反应，我正在急这事呢！！
不知道有没有其它好的，画饼图的控件呢，我这个是动态的与SQL数据库数据连接的！！
