title: Custom legend labels in my rechart chart
body: <p>I have a pretty straight forward data array for my <strong>recharts</strong> component :</p>
  
  <pre><code>{name: '12.1.2011', series1: 4000, series2: 2400, series3: 2400},
  {name: '12.2.2011', series1: 3000, series2: 1398, series3: 2210},
  {name: '12.3.2011', series1: 2000, series2: 9800, series3: 2290}
  </code></pre>
  
  <p>I would like to have labels for the series values in my Legend. Instead of the chart showing me the different colors for "series1", "series2", and "series3".</p>
  
  <p>Of course I could set the actual values I want to use for my legend in the JSON already but this just doesn't look right. Eg :</p>
  
  <pre><code>{name: '12.1.2011', 'My nice long descriptive text': 4000, 'Some other text': 2400, 'Some other descriptive text': 2400},
  {name: '12.2.2011', 'My nice long descriptive text': 3000, 'Some other text': 1398, 'Some other descriptive text: 2210},
  {name: '12.3.2011', 'My nice long descriptive text': 2000, 'Some other text': 9800, 'Some other descriptive text: 2290}
  </code></pre>
  
  <p>I need to map my series level to a descriptive label.</p>
  
  <p>I have looked at <strong>content</strong> in Legend : <a href="http://recharts.org/#/en-US/api/Legend" rel="noreferrer">http://recharts.org/#/en-US/api/Legend</a>, but that seems more concerned with completely rewriting the Legend Component.</p>
