最近一个Webdisk项目需要统计流量数据，于是就找了几个开源免费的chart程序来研究，PHP/SWF Charts 和 FusionCharts Free，不过最终还是选择了Open Flash Char，官方提供了很多实例，而做Webdisk流量统计并不需要多么花哨的东西，OFC2的功能也已经足够强大了。
2.0的版本数据格式完全用json来处理，非常灵活，官方提供了各种接口程序，包括PHP/PHP5、Pear、Python、Java、Dotnet，调用很简单，网页代码（chart.html）如下

chart.html

<html>
<head>
</head>
<body>
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0"
width="800"
height="450" id="graph-2" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="open-flash-chart.swf" />
<param name="quality" value="high" />
<embed src="open-flash-chart.swf" quality="high" bgcolor="#FFFFFF" width="500" height="450" name="open-flash-chart" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>
</body>
</html>

数据文件格式（data.json.txt）如下：

   data.json.txt
