title: position the markers in highcharts to custom coordinate
body: <p>I am teaching myself highcharts and I ran into a situation where </p>
  
  <p>1)I need to position the markers in a spline to a coordinate set of my choice i.e., I want to align the markers horizontally next to each other above the chart instead of positioning them on the graph.</p>
  
  <p>2)I need to able to draw dotted lines from the x axis labels to the markers</p>
  
  <p>3)I need to show the <code>[data]</code> inside the markers</p>

  <p>I tried searching for it in the highcharts API and googled it as well. Couldn't find a solution.</p>
  
  <p>Thanks for any help.</p>
