C3.js - 时间序列无法解析

2022-01-11 00:00:00 time-series parsing javascript c3.js

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

I want to display a time series chart with C3.js using a date in the format 2015-09-17 18:20:34 and the format string '%Y-%m-%d %H:%M:%S' but it fails to parse.

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

如果我在数据和格式中省略时间，它会起作用，但我也需要时间.

It works if I omit the time in the data and in the format but I need the time, too.

推荐答案

我找到了解决问题的方法:

I found the solution to my problem:

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，则必须在 data 对象中使用 xFormat.

The format in the axis object is just to define how the date will be displayed. If you want to specify the format for the date parsing you have to use xFormat in the data object.

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
            }
        }
    }
});
