title: Get hidden parameter from Bar chart
body: <p>I am assigning extra hidden parameters to my bar chart.</p>
  
  <p>["R1", 5.01, "india", "maharashtra"];</p>
  
  <p>How can I show these hidden data in my tooltip on highlight</p>
  
  <p>This is the code which I am using to show tooltip, but I am not able to show the hidden data.</p>
  
  <pre><code>highlighter: {
               tooltipContentEditor: function (ev, seriesIndex, pointIndex, data) {
               return data[3] ;
                  },
               show: true
  }
  </code></pre>
  
  <p>Thanks</p>
