前台代码

<table align="center" border="0" cellpadding="0" cellspacing="0" class="TablebTitle" width="100%">
      
             <tr>
                 <td align="center">
                     
                     <asp:Chart ID="Chart1" runat="server" Width="700px" Height="350px" ImageStorageMode="UseHttpHandler" >
                         
                     </asp:Chart>
                     <div id="txt_Message" runat="server" style="vertical-align:middle; text-align:center; font-size:20px;"></div>
