Highcharts : How to remove the gap between series and vertical axis?

Question

It seems like Highcharts is adding some spacing between the 1. series line start/series line end and the 2. vertical axis.

Please see the jsfiddle link and below sc

Answer 1

check pointPlacement

when pointPlacement is "on", the point will not create any padding of the X axis.

 plotOptions: {
  series: {
    pointPlacement: 'on'
  }
},
