I am right now working on a high-traffic project that will run in a sandbox that doesn't allow me to pull third party JavaScript or use canvas/Flash. Yet I need to generate bar charts from a set of data.
The solution to me was to create the charts from HTML using CSS. There have been some solutions for this problem already but I wanted something very simple and easy to maintain.
方法很简单：
<div >
<?php
$values = '12,3,23.3,44.3,9,20';
$height = 200;
$width = 402;
$bargap = 0;
include('csscharts.php');
?>
<div>
效果：

也支持url传值：
Of course, this can also be turned into a web service - you can get the chart with the following URL:
http://icant.co.uk/csscharts/csscharts.php?values=400,20,30,233,312,78,20,67&height=100&width=600&bargap=0
And if you specify JSON as the format you get it with a callback to a function called csscharts:
