我有一个laravel集合，该集合已按属性“名称”排序。

{
"0":{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
"1":{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
"2":{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
"6":{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
"3":{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
"4":{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
"5":{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
}  

但是，此集合的索引没有更改。索引现在为0、1、2、6、3、4、5。是否可以按照排序的集合的顺序重新索引集合？

所以我想拥有的是：

{
"0":{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
"1":{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
"2":{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
"3":{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
"4":{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
"5":{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
"6":{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
}  

我尝试使用$collection->values()。但是后来我有了：

[
{"id":2,"name":"1","days":["2017-04-06","2017-04-07"]},
{"id":3,"name":"2","days":["2017-04-08","2017-04-09"]},
{"id":4,"name":"3","days":["2017-04-10","2017-04-11"]},
{"id":10,"name":"4","days":["2017-04-12","2017-04-13"]},
{"id":5,"name":"5","days":["2017-04-14","2017-04-15"]},
{"id":6,"name":"6","days":["2017-04-16","2017-04-17"]},
{"id":7,"name":"7","days":["2017-04-18","2017-04-19"]}
]  

我有纬度、经度和高度数据，并想使用 Python 绘制如下图所示的图。地图可以省略，没有必要。

我曾尝试使用mplot3d 多边形图教程，但无法弄清楚如何改变 x 和 y 值，使其不是一条直线。有任何想法吗？
