我有来自我的数据库的数据，我将其转换为 json，如下所示

[{"name":"partner1","cost":"311328","date":"2013-04-01"},
{"name":"partner1","cost":"363780","date":"2013-04-02"},
{"name":"partner1","cost":"364062","date":"2013-04-03"},
{"name":"partner1","cost":"283128","date":"2013-04-04"},
{"name":"partner1","cost":"322608","date":"2013-04-05"},
{"name":"partner2","cost":"425538","date":"2013-04-01"},
{"name":"partner2","cost":"263670","date":"2013-04-02"},
{"name":"partner2","cost":"213192","date":"2013-04-03"},
{"name":"partner2","cost":"378726","date":"2013-04-04"},
{"name":"partner2","cost":"532698","date":"2013-04-05"}]

将此json数据转换为多个系列数据的highcharta标准的最佳方法是什么？

我最后的手段是对数据库进行多次查询来构造数据，但我认为它会消耗服务器时间资源。

感谢您的帮助。

问候，

首先，您应该使用时间戳作为日期（即 Date.UTC() ），而且值应该是数字，而不是字符串。

Ideally you'd transform the data to look like this:

{"partner1": [
  [Date.UTC(2013,3,1), 311328],
  [Date.UTC(2013,3,2), 363780],
...

Note that the month argument to Javascript's Date function starts from 0 (January).
