title: Chart.js: Make part of labels bold
body: <p>I want to make a part of the labels in chartJS bold. I've been looking in the documentation but I cant find of any way. I hope there is someone who can help me out if it is possible at all. :) Below is a picture of how I want it to work. (its made in photoshop)</p>

  <p>So I want to make the "bar total", "bar 1", "bar 2", "bar 3" and "bar 4" bold so the difference with the hours is more clear.</p>
  
  <p>The labels are set in my code like this:</p>
  
  <pre><code>labels: [["bar total", "150 hour"], ["bar 1", "70 hour"], ["bar 2", "30 hour"], ["bar 3", "40 hour"], ["bar 4", "10 hour"]],
  </code></pre>
  
  <p>Iam using ChartJS version 2.3.0.</p>
  
  <p>Any ideas?</p>
