Question

我需要显示所有数据（即使一个数据与另一个重叠），但是当这些数据非常接近时，会自动消失：

documentation推荐allowOverlap，但在我使用时会出现两个值Min和Max，但我只需要Min：

plotOptions: {
    series: {
        dataLabels: {
            enabled: true,
            allowOverlap: true
        }
    }
}

完整代码：

$(function() {

  $('#container').highcharts({

    chart: {
      type: 'columnrange',
      inverted: false,
    },

    xAxis: {
      categories: ['Title 1', 'Title 2', 'Title 3', 'Title 4', 'Title 5'],
      alternateGridColor: '#F6F9FC',
    },

    tooltip: {
      shared: true,
      width: 20,
      formatter: function() {
        var retorno = '<strong>Prices</strong>';

        $.each(this.points, function(i, point) {
          if (point.series.name == 'Min' || point.series.name == 'Med' || point.series.name == 'Max') {
            retorno += '<br /><span style="color:' + point.color + '">\u25CF</span> ' + point.series.name + ': ' + point.y;
          }
        });

        return retorno;
      }
    },

    plotOptions: {
      columnrange: {
        grouping: false,
        pointWidth: 70
      },

    series: [

通过删除您添加的dataLabel格式并添加新格式，我可以使用allowOverlap实现您的目标。

plotOptions: {
  columnrange: {
    dataLabels: {
      allowOverlap: true,
      formatter: function() {
        if (this.y == this.point.low) { 
        //this is needed because highcharts draws 2 boxes for columnrange
        //1 for high series and 1 for low series
          return this.point.low;
        }
      }
    }
  },
}

在小提琴中，我还将每个系列中的一致情节选项移至plotOptions。

＆＃13;

function numberToReal(numero) {
  var numero = numero.toFixed(2).split('.');
  numero[0] = "R$ " + numero[0].split(/(?=(?:...)*$)/).join('.');
  return numero.join(',');
}

$(function() {

  $('#container').highcharts({

    chart: {
      type: 'columnrange',
      inverted: false,
    },

    xAxis: {
      categories: ['Title 1', 'Title 2', 'Title 3', 'Title 4', 'Title 5'],
      alternateGridColor: '#F6F9FC',
    },

    tooltip: {
      shared: true,
      width: 20,
      formatter: function() {
        var retorno = '<strong>Prices</strong>';

        $.each(this.points, function(i, point) {
          if (point.series.name == 'Min' || point.series.name == 'Med' || point.series.name == 'Max') {
            retorno += '<br /><span style="color:' + point.color + '">\u25CF</span> ' + point.series.name + ': ' + numberToReal(point.y);
          }
        });

        return retorno;
      }
    },

    plotOptions: {

修改：感谢this answer我理解为什么要绘制2个标签。我已经更新了这篇文章，现在它只会绘制1个标签。
