title: nvd3.js - unable to change color of line in line chart
body: <p>I am trying to change the colors of different lines of the nvd3 line chart <a href="http://nvd3.org/livecode/index.html#codemirrorNav" rel="nofollow noreferrer">here</a> but am unable to understand how to do so. I would like to change the colors of the 2 lines in the example to green and cyan. I tried</p>
  
  <pre><code>nv.addGraph(function() {
     var chart = nv.models.lineChart()
        .useInteractiveGuideline(true)
        .color(["rgb(0,255,0)","rgb(255,165,0)"]);
  }
  </code></pre>
  
  <p>It worked for scatter chart <a href="https://stackoverflow.com/questions/22992707/nvd3-js-unable-to-change-color-of-symbol-in-scatter-plot#22992996">here</a>. But the color does not change for line chart. Any suggestions.</p>
  
  <p>Thanks</p>
