title: stacked dynamic line graph d3.js
body: <p>Any idea of how I can make this dynamic line graph stacked? <a href="http://jsfiddle.net/praveen_jegan/QBDGB/6/" rel="nofollow">http://jsfiddle.net/praveen_jegan/QBDGB/6/</a></p>
  
  <pre><code>var options = {
      series: {
          stack: true,
          lines: {
              show: true,
              fill: true
          }
      },
  </code></pre>
  
  <p>Does any one have any example?</p>
