title: Chart.js - setting tooltip z-index
body: <p><a href="http://jsfiddle.net/gmannib/j2mwpj43/7/" rel="nofollow">http://jsfiddle.net/gmannib/j2mwpj43/7/</a></p>
  
  <p>^ See the sample fiddle above. Notice how the tooltips for the piechart go underneath the "earth" icon I have in the middle there? Is there a way to set the z-index property of the tooltips to be above the earth icon?  I thought this would work?</p>
  
  <pre><code>race.tooltip.style.zIndex = "5";
  </code></pre>
  
  <p>I'm still learning...thank you for your kind help!</p>
