我有一个堆叠柱形图/散点图，其中一些dataLabels偏离到一侧。我面临的问题是，当我的两个标记开始彼此接近时，它们的dataLabels重叠
我需要始终显示两个标签，那么是否有一种方法可以检测标签重叠的情况，并根据重叠的程度调整y值，从而将底部的标签向下移动？
sample fiddle of the issue

Highcharts.chart('container', {
  chart: {
    type: 'column',
    width: 500
  },
  title: {
    text: 'Stacked column chart'
  },
  xAxis: {
    visible: false,
  },
  yAxis: {
    min: 0,
    visible: false,
    title: {
    },

  },
  legend: {
    layout:"vertical",
    align: "right",
    verticalAlign: "bottom",
    itemMarginTop: 15,
    y: -10,
    x: -50
  },

    enabled: false,
  },

    scatter: {
      marker: {
        symbol: "triangle",
      },
      dataLabels: {
        enabled: true,
        x: -80,
        y: 50,     
        allowOverlap: true,
        useHTML: true,

      pointWidth: 70,
      stacking: 'normal',
      dataLabels: {

      }
    }
  },
  series: [{
    name: '',

          {
            type: "scatter",
            data: [1000],
            color: "#000",
            dataLabels: {
            formatter: function(){
              return "<div class='label-text'>Your goal of <br/>$"+ this.y +"<br/>text</div>"
            },
            }

          },

            data: [900],
            color: "#000",
            dataLabels: {
            formatter: function(){

            },
            }
          }]
});
