/* 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);}
v\:* 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*/<script>function draw3D(arTable,aDiv,asTool,intCol,intRow){ //是否画工具栏asTool如不填为N都认为是Y，跳过左边intCol列和表头intRow列省略为1
