title: Can a chart-line show a legend like chart-radar (for instance)?
body: <p>I have the angularjs chartline:</p>
  
  <pre><code>  &lt;canvas id="line" class="chart chart-line" chart-data="data" chart-series="series" chart-labels="labels" chart-options="options" chart-legend="true"&gt;
      &lt;/canvas&gt;
  </code></pre>
  
  <p>I want it to show legend (series) on the top of chart like how it works at chart-radar.

  <p>I have all settings for this, but it doesn't work properly:</p>
  
  <pre><code>   $scope.options = { legend: { display: true } };
  </code></pre>

  <p>How to do it?</p>
