VML画柱状图、并图、折线图的封装

/*    3D统计图绘图类
功能:根据表格数据绘制统计图
作者:LiuZXIT
完成:2003/9/10
备注:在IE6下测试成功
局限性:1.只能针对于单一二维行列式规则TABLE进行绘制
    2.TABLE内容必须有左标题和上标题,并且右下部分都必须是数据区
不足:没有支持动态定制数据源,例如用一个XML数据包,有些文字太长会出现显示不好

注意点:
    1.htm页面必需包含以下内容
        
<HTML xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office">
        
<STYLE>
        v\:*         
{behavior:url(#default#VML);}
        o\:*         
{ behavior: url(#default#VML) }
        .shape       
{ behavior: url(#default#VML) }
        
</STYLE>
    2.饼形图和柱状图只能针对一行或一列数据,所以在勾选多行或多列时,只会绘制出勾选的最上面行或最左边列
