我是靠谱客的博主玩命魔镜，最近开发中收集的这篇文章主要介绍JavaScript根据数据生成百分比图和柱状图的实例代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

复制代码代码如下:

<HTML> 
<head> 
<title>JS百分比图和柱状图</title>   
<xml:namespace prefix="v"/>   
<style>   
 v:* {behavior=url(#default#VML)}   
</style>   
<style>   
a:hover {color:maroon}   
h2 {color:#006600;   
       margin-top: 0pt;   
       margin-bottom: 0pt}   
h3 {color:#006600;   
       margin-top: 6pt;   
       margin-bottom: 3pt}   
h4 {color:#006600;   
       font-family: Arial;   
       font-size: 10pt;   
       margin-top: 3pt;   
       margin-bottom: 0pt}   
h5 {color:#006600;   
       margin-top: 0pt;   
       margin-bottom: 0pt}   
p  {margin-top: 0pt;   
       margin-bottom: 12pt}
