javascript - 文件加载因浏览器而异

Question

我有一个 d3.js 文件，我正在我的一个应用程序中使用它。

问题: 当我使用 firefox 作为我的浏览器时，它加载正常。但是当我使用 chrome 时，“一月”月份会向下移动，二月会互换，因为它会下降到最左下角。

请引用上面的fiddle链接。在多个浏览器上运行它会提示问题。

为什么浏览器之间会发生这种情况。是否有永久解决方案，使其支持所有浏览器？

上面的 fiddle 中已经包含的 javascript :

您应该通过添加 sort(null) 来禁用排序:

var pie = d3.layout.pie().value(function(d) {
   return d;
}).sort(null); // disable sorting

默认情况下，D3 按值排序，这会导致您的情况出现随机结果。

参见 documentation for D3 3.x here :

pie.sort([comparator])

If comparator is specified, sets the sort order of data for the layout using the specified comparator function. Pass null to disable sorting. If comparator is not specified, returns the current sort order. The sort order defaults to descending value.
