javascript - Highcharts 错误 15

Question

我正在尝试使用 highcharts 来表示这些数据:

[
  {
    "name": "c1",
    "data": [
      [
        -52587360000000,
        2
      ],
      [
        -52590038400000,
        1
      ],
      [
        -52611724800000,
        1
      ],
      [
        -52622611200000,
        1
      ],
      [
        -52655184000000,
        1
      ],
      [
        -52663392000000,
        2
      ],
      [
        -52855545600000,
        2
      ]
    ]
  },
  {
    "name": "c2",
    "data": [
      [
        -52587360000000,
        2
      ],
      [
        -52590038400000,
        1
      ],
      [
        -52611724800000,
        1
      ],
      [
        -52622611200000,
        1
      ],
      [
        -52655184000000,
        1
      ],
      [
        -52663392000000,
        2
      ],
      [
        -52855545600000,
        2
      ]
    ]
  },
  {
    "name": "c3",
    "data": [
      [
        -52587360000000,
        2
      ],
      [
        -52590038400000,
        1
      ],
      [
        -52611724800000,
        1
      ],
      [
        -52622611200000,
        1
      ],
      [
        -52655184000000,
        1
      ],
      [
        -52663392000000,
        2
      ],
      [
        -52855545600000,
        2
      ]
    ]
  }
]

这是我的尝试:

container.highcharts({
    title: {
        text:"Name"
    },
    xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
            month: '%e. %b',
            year: '%b'
        }
    },
    yAxis: {
        title: {
            text: 'Occurrence'
        },
        plotLines: [{
            value: 0,
            width: 1,
            color: '#808080'
        }]
    },
    tooltip: {
        valueSuffix: 'Occurrence'
    },
    legend: {
        layout: 'vertical',
        align: 'right',
        verticalAlign: 'middle',
        borderWidth: 0
    },
    series: response // 
});

如您所见，图表未正确显示: 在控制台中我得到这个错误:

"Highcharts error #15: www.highcharts.com/errors/15"

我的错误是什么？

正如 link in the error message 会告诉你的那样:

Highcharts expects data to be sorted

This happens when you are trying to create a line series or a stock chart where the data is not sorted in ascending X order. For performance reasons, Highcharts does not sort the data, instead it is required that the implementer pre-sorts the data.

在您的情况下，第一个系列中的 x 值是:

-52587360000000
-52590038400000
-52611724800000
-52622611200000
-52655184000000
-52663392000000
-52855545600000

只看前两个，很明显 -52587360000000 比 -52590038400000 更小(更负)。看来您实际上已经对它们进行了反向排序。也就是说，最大的数字在前，然后它们越来越小(更负)。

您必须更改系列中数据的顺序，以便首先是最小的数字，然后是值增加。
