javascript - C3.js - 时间序列无法解析

Question

我想使用 C3.js 显示时间序列图表，使用格式为 2015-09-17 18:20:34 的日期和格式字符串 '%Y-%m-%d %H:%M:%S' 但解析失败。

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

02:26:44.891 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

如果我在数据和格式中省略时间，它会起作用，但我也需要时间。

我找到了我的问题的解决方案:

axis 对象中的格式只是定义日期的显示方式。如果您想指定日期解析的格式，您必须在 data 对象中使用 xFormat。

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
            }
        }
    }
});
