title: How to get Highcharts X-Axis Categories starting at the left most point
body: <p>I have a Highcharts area chart, with string categories on the X-Axis.
  I want the chart to start at the left most edge of the x-axis and end at the rightmost edge, without any padding. In the image below, the red arrows show the spacing that I want to get rid of. Without text categories this is easily achievable, but with I just can't seem to figure it out.
  Any help appreciated, thanks.</p>
