C3.js - 时间序列无法解析

Question

我想显示一个时间序列图表,C3.js使用格式2015-09-17 18:20:34和格式字符串中的日期,'%Y-%m-%d %H:%M:%S'但无法解析.

我的代码:

var chart = c3.generate({
    bindto: '#chart',
    data: {
      x: 'times',
      columns: [
        ['times','2015-09-17 18:20:34','2015-09-17 18:25:42','2015-09-17 18:30:48'],
        ['data','1539','1546','1546','1550']
      ]
    },
    axis: {
        x: {
            type: 'timeseries',
            tick: {
                format: '%Y-%m-%d %H:%M:%S'
            }
        }
    }
});

我收到以下错误:

02:26:44.889 Failed to parse x '2015-09-17 18:20:34' to Date object c3.min.js:1:21943
02:26:44.889 Failed to parse x '2015-09-17 18:25:42' to Date object c3.min.js:1:21943
02:26:44.890 Failed to parse x '2015-09-17 18:30:48' to Date object c3.min.js:1:21943
02:26:44.890 Failed to parse x '2015-09-17 18:20:34' to Date object c3.min.js:1:21943
02:26:44.891 Failed to parse x '2015-09-17 18:25:42' to Date object c3.min.js:1:21943
02:26:44.892 Failed to parse x '2015-09-17 18:30:48' to Date object c3.min.js:1:21943

如果我省略数据和格式的时间,但我也需要时间,它可以工作.

我找到了解决问题的方法:

axis对象中的格式只是定义日期的显示方式.如果要指定日期解析的格式,则必须xFormat在data对象中使用.

var chart = c3.generate({
    bindto: '#chart',
    data: {
      x: 'times',
      xFormat: '%Y-%m-%d %H:%M:%S', // how the date is parsed
      columns: [
        ['times','2015-09-17 18:20:34','2015-09-17 18:25:42','2015-09-17 18:30:48'],
        ['data','1539','1546','1546','1550']
      ]
    },
    axis: {
        x: {
            type: 'timeseries',
            tick: {
                format: '%Y-%m-%d %H:%M:%S' // how the date is displayed
            }
        }
    }
});
