title: HighCharts - Remove space between series on stacked bar
body: <p>I have a HighCharts chart to display some information. I have stacked information for each day. Each entry is unique -> I cannot use a single series.</p>
  
  <p>The problem is: between two days, there's a huge space and I have no idea how to decrease or remove this.
  There's no effect when I play with the PlotOptions.
  I think the reason is my xAxis-Handling, because if I use the "normal way" to declare the xAxis categies, there's no problem.</p>
