title: jqplot with IE8 not working
body: <p>i am getting a js-error when i try to init graphs with jqplot under IE8.</p>
  
  <p>The error is at:</p>
  
  <pre><code>return window.G_vmlCanvasManager.initElement(P)
  </code></pre>
  
  <p>in the jquery.jqplot.min.js file.</p>
  
  <p>The error is about: "the property initElement is undefined or null"</p>
  
  <p>How can i fix that?</p>
  
  <p>Moreover the same error appears at the <a href="http://www.jqplot.com/tests/line-charts.php" rel="nofollow noreferrer">official site</a> of jqplot.</p>
  
  <p>I am using the IE11 with IE8 Emulator Mode.
  IE>8 => no problems.</p>
