mschart asp chart 用法，包括前台写法与后台写法，还有click事件，如何触发。
纯后台动态生成aspchart ，这种方式没办法实现chart中click事件。click事件点击没有反应，用第二种可以实现点击事件。
两种方式实现同一种效果图：
第一种写法：后台动态生成aspchart
前台代码：
<div>
<div class="h_10">
</div>
<table cellpadding="" cellspacing="" border="" width="100%">
<tr>
<td> 时间：<input id="S_BeTime" type="text" class="mycalendar" name="S_BeTime" style="width: 90px;" value="" runat="server" />至
<input id="S_EndTime" type="text" class="mycalendar" name="S_EndTime" style="width: 90px;" value="" runat="server" /> <asp:Button ID="btnSeach" runat="server" Text="查询" OnClick="btnSeach_Click" class="mybutton" Width="60px" /> </td>
</tr>
