Crossfilter转换示例

Question

我尝试使用crossfilter

转换以下json数据

[{ Company: "Company 1",  Min: 1, Max: 5, Year: 2013 },
{ Company: "Company 1",  Min: 2, Max: 6, Year: 2014 },
{ Company: "Company 2",  Min: 3, Max: 7, Year: 2013 },
{ Company: "Company 2",  Min: 4, Max: 8, Year: 2014 }]

我的预期结果是： 第一次转变

(Min) = [
{ key: "Company 1", 2013: 1, 2014: 2 }
{ key: "Company 2", 2013: 3, 2014: 4 }
]

OR

(Max) = [
{ key: "Company 1", 2013: 5, 2014: 6 }
{ key: "Company 2", 2013: 7, 2014: 8 }
]

第二次转换

(Min) = [
{ "Company 1": 1, "Company 2": 3, key: 2013 },
{ "Company 1": 2, "Company 2": 4, key: 2014 },
]

OR

(Max) = [
{ "Company 1": 5, "Company 2": 7, key: 2013 },
{ "Company 1": 6, "Company 2": 8, key: 2014 },
]

我没有办法做到这一点。有人为此提供了一个基本的例子吗？ 或者是crossfilter.js做错了吗？
