[q888710631]

只有一个点位数据时不显示tooltip，多于一个点位时正常

$.get(
  ROOT_PATH + '/data/asset/data/life-expectancy-table.json',
  function (data) {
    option = {
      tooltip: {},
      xAxis3D: {
        type: 'value',
        name: 'X',
        min: 0,
        max: 300,
        interval: 100,
        axisLabel: {}
      },
      yAxis3D: {
        type: 'value',
        name: 'Y',
        min: 0,
        max: 300,
        interval: 100,
        axisLabel: {}
      },
      zAxis3D: {
        type: 'value',
        name: 'Z',
        min: 0,
        max: 300,
        interval: 100,

      },
      grid3D: {},
      series: [
        {
          name: 'point',
          type: 'scatter3D',
          data: [
            [0, 0, 0],
            [100, 150, 200]
          ],
          itemStyle: {
            color: 'red',
            borderColor: 'white',
            borderWidth: 1
          }
        }
      ]
