Y轴Axaw的日期时间

Question

我正在构建热图图表的中间，但是我在我的json文件中从时间戳数据在Y轴添加日期时间时出现问题，它在我的Y轴图表中只显示00：00：00：001。 / p>

这是我的代码

    $(document).ready(function() {
      var options = {
        chart: {
          renderTo: 'container',
          type: 'heatmap'
        },
        xAxis: {
          tickPixelInterval: 1000,
          categories: []
        },
          yAxis: {
          type: 'datetime'
                },
        legend: {
          align: 'right',
          layout: 'vertical',
          margin: 0,
          verticalAlign: 'top',
          symbolHeight: 280
        },
        colorAxis: {
          stops: [
            [0, '#3060cf'],
            [0.5, '#fffbbc'],
            [0.9, '#c4463a']
          ],
          min: -5
        },
        plotOptions: {
          series: {
            turboThreshold: 0
          }
        },
        series: [{
          dataLabels: {
            enabled: true,
            color: '#000000'
          }
        }]
      };

      var ajaxCounter = 0,
        dataArr = [],
        intervalId = setInterval(function() {
          $.getJSON('test.json', function(data) {
              var categories = [],
                prevCat = -1,
                numb = -1;

              Highcharts.each(data, function(xvals, i) {
                if (prevCat !== xvals[0]) {
                  numb++;

                  prevCat = xvals[0];
                  categories.push((xvals[0]));
                  dataArr.push([numb, ajaxCounter, xvals[2]]);
                } else {
                  dataArr.push([numb, ajaxCounter, xvals[2]]);
                }
              });
              ajaxCounter++;
              options.xAxis.categories = categories;

              options.series[0].data = dataArr;
              var chart = new Highcharts.Chart(options);

              if (ajaxCounter === 24) {
                clearInterval(intervalId);
              }
          });
        }, 10000);
    });

这是我的json文件

    [
    [100,1474633760,0],
    [200,1474633760,0],
    [300,1474633760,2471.0],
    [400,1474633760,0],
    [500,1474633760,0],
    [600,1474633760,1951.0],
    [700,1474633760,0],
    [800,1474633760,0],
    [900,1474633760,2125.0],
    [1000,1474633760,0]
    ]

谢谢你的关注，我希望你们能帮助我的小项目
