title: How to prevent my stacked series from being in reverse order?
body: <p>I tried an <a href="http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/plotoptions/series-stacking-line/" rel="nofollow noreferrer">example of stacked series on JSFiddle</a> but according to me, series are reversed when stacked:</p>
  
  <pre><code>$(function () {
      $('#container').highcharts({
          chart: {
          },
          xAxis: {
              categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
          },
  
          plotOptions: {
              series: {
                  stacking: 'normal'
              }
          },
  
          series: [{
              data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
          }, {
              data: [144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 106.4, 129.2]
          }]
      });
  });
  </code></pre>
  
  <p>The first line in blue should be drawn first (January : 29.9), and the second should be added to this one (January : 29.9 + 144 = 173.9 ).</p>
  
  <p>Is there a way to get series in the right order when they are stacked?</p>
