Question

我有来自我的数据库的数据，我将转换为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"}]

如何将这个json数据转换为多系列数据的highcharta标准是最好的？

我的最后一招是对db进行多次查询来构建数据，但我认为它会占用服务器时间资源。

感谢您的帮助。

的问候，

Answer 1

理想情况下，您将数据转换为如下所示：

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

请注意，Javascript日期函数的月份参数从0（1月）开始。

Answer 2

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