title: Highcharts: Column chart with empty data
body: <p>I have created chart with dynamic data. And it is getting null values for 2 columns.</p>
  
  <p>see this fiddle : jsfiddle.net/xj6ms/2/</p>
  
  <p>I want to remove empty columns, so that it will arrange other columns properly.</p>
  
  <p>Is it possible? </p>
  
  <p>Thank you,</p>
