title: Make highchart columns extend to edge
body: <p>I have not been able tow work out how to extend my column highchart right to the very edge.</p>
  
  <p>In the image below, the blue area is the highcharts div, and the red area is the "wasted space" I want to elimiate.</p>
  
  <p>What is the best way to do this?</p>
