title: NVD3: How to get values from tooltip or legend instead of labels?
body: <ul>
  <li><p>The problem with using labels is that if a slice is too small the labels doesn't shows up and therefore, getting the value of label during onClick event fails</p></li>
  <li><p>The problem is reproduced here <a href="http://plnkr.co/edit/3rCHWnxW7EFPXxWHLo96?p=preview" rel="nofollow noreferrer">http://plnkr.co/edit/3rCHWnxW7EFPXxWHLo96?p=preview</a>. You will see that for <strong>Taxes</strong> the label is missing and therefore I can't get its value on click event

  </ul>
  
  <p><strong>what would be awesome?</strong>  </p>
  
  <ul>
  <li>If I can get the value from tooltip or legend instead of labels because labels are not a good idea to get values</li>
  <li>Because I pass the value of label onclick to display other graph</li>
  </ul>
