Chartist plugin tooltip : Adding the label in the tooltip
<p>Assuming I have this kind of data for my pie chart and I'm gonna use <a href="https://github.com/Globegitter/chartist-plugin-tooltip" rel="nofollow">GlobeGitter's Chartist Plugin Tooltip</a></p>

<pre><code>        var data = {
            labels: ['ra','rb','rc','rd','re','rf'],
            series: [5, 3, 4, 1, 6, 4]
        };
</code></pre>

<p>How can I add the value of labels in my tooltip? Sample text of tooltip</p>

<blockquote>
  <p>ra : 5</p>
