title: Highcharts x-axis category overlap
body: <p>The dates are overlapping in x-axis bar on the bottom. What is the best solution to resolve this?</p>
  
  <p>If the date count is over 13, then I'm fine with having no category labels, but I at least need the dates on the point mouseover.</p>
  
  <p>I've tried the formatter function, but it doesn't work, it gives me numbers and not a date range.</p>
  
  <pre><code> xAxis: {
        categories:{
             formatter: function() {
                 ['5/16/2013','7/1/2013','7/3/2013','7/2/2013','7/4/2013','7/6/2013','7/7/2013','7/8/2013','7/15/2013','5/22/2013','7/9/2013','7/10/2013','7/11/2013','7/13/2013']
             }
        }
   },
  </code></pre>
  
  <p>I've included a jsfiddle to show you how it looks.</p>
