open flash chart 2確實是一個很不錯的網頁圖表產生組件，並且是免費的。但是目前的版本卻有一個問題，就是open flash chart 2在IE下重新整理無法改變圖表，狗遍網路，功夫不負有心人，找到這篇博文：http://java-007.javaeye.com/blog/537832，並在他的啟發下，解決在php中open flash chart 2的重新整理問題。
官方有個範例程式碼大致如下：
<html>
<head>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
swfobject.embedSWF(
"open-flash-chart.swf", "pie_chart",
"300", "300", "9.0.0", "expressInstall.swf",
{"data-file":"pie-chart.php"} );
swfobject.embedSWF(
"open-flash-chart.swf", "line_chart",
"500", "300", "9.0.0", "expressInstall.swf",
{"data-file":"line-dot.php"} );
</script>
</head>
<body>
<p>Hello World</p>
<div id="pie_chart"></div>
<div id="line_chart"></div>
</body>
</html>
我們把代碼改成如下樣子：
<html>
<head>
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
var string1="pie-chart.php?ram1="+Math.random();
var string2="line-dot.php?ram2="+Math.random();
swfobject.embedSWF(
"open-flash-chart.swf", "pie_chart",
"300", "300", "9.0.0", "expressInstall.swf",
{"data-file":string1} );
swfobject.embedSWF(
"open-flash-chart.swf", "line_chart",
"500", "300", "9.0.0", "expressInstall.swf",
{"data-file":string2} );
</script>
</head>
<body>
<p>Hello World</p>
<div id="pie_chart"></div>
<div id="line_chart"></div>
</body>
</html>
以上紅色代碼為改動部分，通過Math.random()在串連後面追加一個隨機參數，使得IE每次重新整理時都認為是在請求一個新網頁，這樣重新整理時flash圖表也跟著重新整理了。
