title: Dashboard using highcharts.js
body: <p>I'm trying to build a dashboard using highcharts.js(multiple charts are displayed on a page), the data for these charts are fetched via ajax. Each of these charts can be refreshed independently. Initially when I was trying to get this working I was getting error #16 and I figured out that HighCharts.js was included and the ajax response was sending back HighCharts again and hence this error was being thrown by HighCharts.</p>
  
  <p>To circumvent this I added js code to check if HighCharts was already defined and if it was I set it to null  </p>
  
  <pre><code>if(window.Highcharts){
      window.Highcharts = null;
  }
  </code></pre>
  
  <p>This seemed to solve the problem, but however I now see that when I refresh one chart the other chart(s) on the dashboard seem to have some rendering issues - a part of the other chart(s) seems to have been stripped off.</p>
  
  <p>Please let me know if what I'm doing is right, also please let me know a better way in which I can avoid loading HighCharts is its already loaded.</p>
