JQuery插件——flash图表组件

      fusioncharts是一个基于Flash的图表组件，可以用来提供数据驱动的动态图标，fusioncharts可用于任何网页脚本语言如， HTML格式，JSP技术等等。提供交互式和强大的动态图标，fusioncharts充分利用流体美丽的Flash为模板，使用XML作为其数据接口，创造紧凑，互动和真正的动态图表

 

      现结合 jquery 封装成组件，方便调用。

     

      该组件包括

            jquery-1.3.2.min.js; (jquery核心类库)

            jquery.flash.js:  (flash 类)

            flashdemo.js      (js与html 分离)

            flashdemo.html

            swf 文件（Column3D.swf、Line.swf、Pie3D.swf）

 

      运行效果图：

           

 

 

    具体实现如下：

    jquery.flash.js

      注意点：swf文件路径的配置353行
