title: Highcharts Bar Chart: possible to combine datapoints inside dataLabels?
body: <p>I have a Highcharts horizontal bar chart with two series.  Is it possible to combine the grouped data points into each data label so that they appear together, e.g. 1.00 / 2.3?</p>
  
  <p>CODE:</p>
  
  <pre><code>var labels = [
      'AAA/Aaa',
      'AA+/Aa1',
      'AA/Aa2',
      'AA-/Aa3',
      'A+/A1',
      'A/A2',
      'A-/A3'
  ];
  var theData = [
      {
          name: 'Company 1',
          data: [0.576,7.617,12.101,18.839,18.022,7.644,9.72]
      },
      {
          name: 'Company 2',
          data: [4.123,12.862,14.561,13.754,12.226,11.135,7.51]
      }
  ];
  </code></pre>
  
  <p>HIGHCHARTS CONFIG:</p>
  
  <pre><code>$(function () {
      $('#container').highcharts({
          chart: {
              type: 'bar'
          },
          legend: {
              align: 'center',
              layout: 'horizontal',
              verticalAlign: 'bottom'
          },
          plotOptions: {
              series: {
                  dataLabels: {
                      enabled: true,
                      formatter: function() {
                          var out = '&lt;span class="col-chart-label"&gt;';
                          out +=  this.y + ' / ' + this.y;
                          out += '&lt;/span&gt;'
                          return out;
                      },
                      useHTML: true
                  }
              }
          },
          series:  theData,
          tooltip: {
              enabled: false
          },
          xAxis: {
              categories: labels,
              labels: {
                  formatter: false,
                  overflow: 'justify',
                  rotation: false
              },
              reversed: true
          }
      });
  });

  <p>The demo is here:

  <p>To reiterate, there should be one data label per pair of bars with the top bar as the first value and the bottom bar as the second value, separated by "/"</p>
  
  <p>Thanks a lot.</p>
