d3.js - 在 Crossfilter 中使用过滤器

Question

我刚刚开始使用 crossfilter 和 d3.js ......我正在尝试 API 引用中给出的一些片段......我有以下数据

var payments = crossfilter([
  {date: "2011-11-14T16:17:54Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T16:20:19Z", quantity: 2, total: 190, tip: 100, type: "tab"},
  {date: "2011-11-14T16:28:54Z", quantity: 1, total: 300, tip: 200, type: "visa"},
  {date: "2011-11-14T16:30:43Z", quantity: 2, total: 90, tip: 0, type: "tab"},
  {date: "2011-11-14T16:48:46Z", quantity: 2, total: 90, tip: 0, type: "tab"},
  {date: "2011-11-14T16:53:41Z", quantity: 2, total: 90, tip: 0, type: "tab"},
  {date: "2011-11-14T16:54:06Z", quantity: 1, total: 100, tip: 0, type: "cash"},
  {date: "2011-11-14T16:58:03Z", quantity: 2, total: 90, tip: 0, type: "tab"},
  {date: "2011-11-14T17:07:21Z", quantity: 2, total: 90, tip: 0, type: "tab"},
  {date: "2011-11-14T17:22:59Z", quantity: 2, total: 90, tip: 0, type: "tab"},
  {date: "2011-11-14T17:25:45Z", quantity: 2, total: 200, tip: 0, type: "cash"},
  {date: "2011-11-14T17:29:52Z", quantity: 1, total: 200, tip: 100, type: "visa"}
]);

我可以通过类型创建维度作为

var paymentsByTotal = payments.dimension(function(d) { return d.type; });

我的问题是如何过滤字符串数组。我试过:

paymentsByTotal.filterRange(["cash","visa"]);

但是我没有得到预期的结果!

有什么建议？

Answer 1

Crossfilter.js 的master 分支中的源代码，没有提供过滤器联合的规定，你必须从Jason Davies' union branch 获取代码。 .

那么，你应该可以做 paymentsByTotal.filter("cash","visa");并获得所需的输出。
