title: Highcharts: Dynamic drilldown (stacked chart) in Combo Dual Axes
body: <p>Well I have this issue, this is my jsfiddle: <a href="http://jsfiddle.net/pLDeq/1/" rel="nofollow">http://jsfiddle.net/pLDeq/1/</a></p>
  
  <p>has you can see, when I clicked in a column I change to a stacked chart, but sometimes I will have 3 columns, 5, etc, my question is, exists a way to detect this? </p>
  
  <pre><code>if (drilldown) { 
       setChart([drilldown.name, drilldown.name1, drilldown.name2, drilldown.name3, drilldown.name4, drilldown.name5],  drilldown.categories,  [drilldown.data, drilldown.data1, drilldown.data2, drilldown.data3, drilldown.data4, drilldown.data5], drilldown.color, [drilldown.type]); 
  }
  </code></pre>
  
  <p>Another thing that I cant resolve yet is, why I can't get the name in the drilldown for the legends and the tooltip? And can I formatter the tooltip for the drilldown?'</p>
