highchart 的新手并坚持使用 datetime 类型，数据未绘制

Question

我试图从这个演示中理解

https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/line-time-series

通过仅更改数据和运行它，但它不起作用，根据我的理解，日期时间类型应该是毫秒，对吗？

此测试数据来自 mysql，使用命令 UNIX_TIMESTAMP(dateTime_Field)*1000

        Highcharts.chart('container', {
            chart: {
                zoomType: 'x'
            },
            title: {
                text: 'USD to EUR exchange rate over time'
            },
            subtitle: {
                text: document.ontouchstart === undefined ?
                    'Click and drag in the plot area to zoom in' : 'Pinch the chart to zoom in'
            },
            xAxis: {
                type: 'datetime'
            },
            yAxis: {
                title: {
                    text: 'Exchange rate'
                }

Answer 1

您的数据结构看起来是正确的，但您需要使用数组而不是字符串。您可以使用JSON.parse进行转换。

  series: [{
    type: 'area',
    name: 'USD to EUR',
    data: JSON.parse('[[1015174800000, 62], [1044810000000, 86], ...]')
  }]
