body: <p>At this code javascrip give an error</p>
  
  <pre><code>$.each(JSON, function(i, array) {                        
      chart.series[i].name = array.teamName;
      chart.series[i].setData(array.teamPower, true);
  });
  </code></pre>
  
  <p>I must define the chart.series[i] because it say "Cannot set property 'name' of undefined"
  but i can't find a way in order to do this.</p>
  
  <p>Because it fonction runs with requestData so it came after chart determine with options</p>

      chart = new Highcharts.Chart(option);       
  }
  </code></pre>
