柱状图问题

其实将每一个柱图理解为表格，生成表格也是一样的。http://www.yygs.com/dcbd/wsdc.php
源程序如下：
<?php
//连接数据库
$sql="select * from wzdcedit";
$result=mysql_query($sql,$cn);
$record=mysql_fetch_array($result);
$onecount=$record["oneitem"];
$twocount=$record["twoitem"];
$threecount=$record["threeitem"];
$fourcount=$record["fouritem"];
$totalcount=$onecount+$twocount+$threecount+$fourcount;
$onepercent=round(($onecount*100/$totalcount));
$twopercent=round(($twocount*100/$totalcount));
$threepercent=round(($threecount*100/$totalcount));
$fourpercent=round(($fourcount*100/$totalcount));
mysql_close();
?>

soniclee(疯宝宝) ，你要是不会，可以不写。很多兄弟是喜欢帮助别人的。人的知识有长短，小弟才疏学浅，正在学编程，你开始学编程的时候也是照着例子写吧？！计算机的组成道理很简单，不就是硅和铜搀和在一起储存0，1信息吗？酸奶的制作过程很简单，不就是找牛，挤奶，然后发酵吗？你为什么不用自己作的计算机编程，吃自己弄的酸奶？
