.NET MSChart应用的一个简单例子 （转）
这几天都在研究微软才发布的MSChart图表工具，我写了简单的例子发上来让大家看看。
使用前需要做得工作：1.把.net平台升级为3.5sp1的。
2.安装MSChart控件。
3.在使用时必须在项目中的web.canfig中添加一些内容；
Code<appSettings>
<add key="ChartImageHandler" value="Storage=file;Timeout=20;Url=~/tempImages/;"/>
</appSettings>
<httpHandlers>
<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"/>
</httpHandlers>
<handlers>
<remove name="ChartImageHandler"/>
<add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</handlers>
这样我们就可以使用控件来画图表了
我在实例中主要对实例2做了详细的说明，实例1是ms上的例子！

实例2的图片效果：
图片不是很花哨，但是看起来很整洁！有什么意见随便提，我第一次发首页！！！！
