VML z-index 问题

[jonefy]

我试图做一个圆环的效果，将一个<v:oval的圆放置在两个报表中间！

我试图将一个 <v:oval 显示在由 <v:shape 和<v:Rect 生成的饼状报表下


但是我设置z-index 为-1 则在最底下，设置为正数则显示在最上层


望各位不吝赐教！

z-index只对绝对定位管用。

在加上position:absolute;把这两个饼图

设置的都是position:absolute;

那你就让在上面的数值大一些，下面的用1就行了，别用-1，这样试试~·

问题已解决！ 我在最上层的饼状报表上加了一个和它样式一样的iframe并且隐藏它！

谢谢MuBeiBei 热心回答！ 结贴给分！
