title: How to add title inside doughnut chart in Angular Chart?
body: <p>I'm using a <a href="http://jtblin.github.io/angular-chart.js/#doughnut-chart" rel="nofollow noreferrer">doughnut chart</a> in <a href="http://jtblin.github.io/angular-chart.js/" rel="nofollow noreferrer">Angular Chart</a>. I want to place some text in the center of the doughnut. I've read <a href="https://stackoverflow.com/questions/20966817/how-to-add-text-inside-the-doughnut-chart-using-chart-js">this question's</a> answers but none of them works for me, because I have tooltips and for some reason the text disappears when you hover the chart. Moreover, I need to provide this text from "outside" - custom text, e.g. a title.</p>
  
  <p>So, my idea is to have something like:</p>
  
  <pre><code>var options = {
      innerTitle = "This should be placed in the center of the doughnut"
  }
  </code></pre>

  <p>Any ideas?</p>
