Highcharts、日期时间、时间戳。当轴的类型为 'datetime' 时,日期需要什么格式?

Highcharts, datetime, timestamp. What format of date needs when axis has type 'datetime'?

我是 Highcharts 的新手,遇到了一个问题。当 axis 类型为 'datetime' 时,它需要什么样的日期格式,只有时间戳? 例如:

const options: Options = {
        chart: {
            type: 'column',
        },
        xAxis: {
            crosshair: false,
            type: 'datetime', 
            title: {
                text: 'test X,
            },
            labels: {
                format: '{value:%m.%Y}', // here I formate to date
            },
        },
        yAxis: {
            title: {
                text: 'test Y',
            },
        },
        series: [
            {
                name: 'test 1',
                data: [
                    [1483232400000, 1.4],
                    [1483491600000, 5.5],

                ],
            },
            {
                name: 'test 2',
                data: [
                    [1483232400000, 2.4],
                    [1483491600000, null],

                ],
            },
        ],

    };

但是我可以像这样用字符串传递数据吗?:

data: [
        ['2021/12/28', 1.4],
        ['2022/01/28', 1.3],...

或者像这样:

data: [
        ['28.12.2021', 1.4],
        ['28.01.2022', 1.3],...

根据文档:

type

The type of axis. Can be one of linear, logarithmic, datetime or category. In a datetime axis, the numbers are given in milliseconds, and tick marks are placed on appropriate values like full hours or days. In a category axis, the point names of the chart's series are used for categories, if not a categories array is defined.

您需要使用以毫秒为单位的时间戳:

  series: [{
    data: [
      [new Date('2021/12/28').getTime(), 1.4],
      [new Date('2022/01/28').getTime(), 1.3],
      [new Date('2022/02/28').getTime(), 1.3]
    ]
  }]
