我一直在尝试创建一个图表来显示世界不同地区发生的事件.所以我基本上去了两个图1)d3谷歌图( http://bl.ocks.org/mbostock/899711)的组合,通过地图和jquery flot饼图( http://people.iola.dk/olau/flot/examples/pie.html)显示区域来映射事件.我已将所有相应的lattiti经度值存储到数组中,并且在这些值的基础上附加地图上的标记.所以基本上我会在< foriegnobject>的帮助下在相应的标记上创建一个xhtml：div空间.一旦创建了这些div,我将为每个相应的div元素添加饼图.所以图形创建成功,饼图的“plotclick”功能,以捕捉饼图上的点击.在所有饼图上都没有检测到该点击功能.在大多数饼图中,单击切片,调用相应的单击功能.它同样也适用于悬停.

问题只出在firefox和我使用最新版本的firefox 22.0.该图在Chrome中运行良好..

我添加了图表的截图.
它是一个已知问题还是与图形创建方法有关？

// EDIT : (Code Added)
