title: xAxis - point specific label positions
body: <p>Is there a way to have a point specific positionning of the xAxis labels ? </p>
  
  <p>I am using a waterfall chart and for some bars I would like the label to appear directly under the bar like below :</p>
  
  <p><a href="https://i.stack.imgur.com/2z9Va.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2z9Va.png" alt="enter image description here"></a></p>
  
  <p>I have found the following code in the xAxis plotOptions but at this point I don't see how I can acces the info on the bottom of the chart.</p>
  
  <pre><code>xAxis: {
      labels: {
          y:-100 //label's y position 
      }
  },
  </code></pre>
