Question

下面是热图图表的演示示例，

系列名称对我不显示，我想念什么？

series: [{
    name: 'Sales per employee',
    borderWidth: 1,
    data: [[0, 0, 10], [0, 1, 19], [0, 2, 8], [0, 3, 24], [0, 4, 67], [1, 0, 92], [1, 1, 58], [1, 2, 78], [1, 3, 117], [1, 4, 48], [2, 0, 35], [2, 1, 15], [2, 2, 123], [2, 3, 64], [2, 4, 52], [3, 0, 72], [3, 1, 132], [3, 2, 114], [3, 3, 19], [3, 4, 16], [4, 0, 38], [4, 1, 5], [4, 2, 8], [4, 3, 117], [4, 4, 115], [5, 0, 88], [5, 1, 32], [5, 2, 12], [5, 3, 6], [5, 4, 120], [6, 0, 13], [6, 1, 44], [6, 2, 88], [6, 3, 98], [6, 4, 96], [7, 0, 31], [7, 1, 1], [7, 2, 82], [7, 3, 32], [7, 4, 30], [8, 0, 85], [8, 1, 97], [8, 2, 123], [8, 3, 64], [8, 4, 84], [9, 0, 47], [9, 1, 114], [9, 2, 31], [9, 3, 48], [9, 4, 91]],
    dataLabels: {
        enabled: true,
        color: '#000000'
    }
}]

在问题下方的注释中咨询了主题之后，可以使用Axis.title方法在Chart.events.load事件函数内将系列名称设置为setTitle()。然后应根据您当前的系列名称在每个图表负载处动态设置它。这是显示如何实现的代码：

chart: {
  events: {
    load() {
      var chart = this
      var seriesName = chart.series[0].name

      chart.xAxis[0].setTitle({ text: seriesName, style: { fontWeight: 'bold' } })
    }
  }
}
