title: Chartjs not working in IE8, issue with canvas element even after including excanvas
body: <p>I have been working on <a href="http://www.chartjs.org/" rel="nofollow">chartjs</a>.
  It works fine in IE10 but when I change the document mode to IE8 it throws the below error</p>
  
  <pre><code> Object doesn't support property or method 'getContext'  line.html, line 43 character 2
  </code></pre>
  
  <p>I tried all the solutions suggested <a href="https://github.com/nnnick/Chart.js/issues/89" rel="nofollow">here</a></p>
  
  <p>I included excanvas.js but no luck. </p>
  
  <p>You can check the demo <a href="http://www.chartjs.org/docs/" rel="nofollow">here</a> , visit this page and change the document mode to IE8. But the <a href="http://www.chartjs.org/" rel="nofollow">parent site</a> works fine when we change browser mode and document mode to IE8. Please help me fix this issue</p>
