How to add Tooltip Functionality to X-axis labels in highcharts
<p>how can show Tooltip on formatted X-Axis label. This tooltip must contain un-formatted text. 
Refer this sample <a href="http://jsfiddle.net/xeHyB/2/" rel="nofollow">fiddle</a> which depicts the same scenario.</p>

<pre><code>labels:{
                formatter: function(){
                    if (this.value.length &gt; 10){
                        return this.value.substr(0,10) + "...";
                    }else{
                         return this.value;   
                    }                        
                }
            }
</code></pre>

<p>Thank you :)</p>
