Reply To: Hover effect – vertical line over datapoint

[Bivek Singh]

@mhoward1,

You can add stripLine for drawing a vertical line along axisX as shown in the code snippet below –

function stripLineHandler(position){
  if(!chart.options.axisX){
    chart.options.axisX ={};
  }
  if(!chart.options.axisX.stripLines){
    chart.options.axisX.stripLines = [];
  }
  chart.options.axisX.stripLines[0] = {
    value : position,
    thickness: 2,
    //color:"red",
    showOnTop: true,
    label: (new Date(position).getDate()+"-"+new Date(position).getHours()+":"+new Date(position).getMinutes()+":"+new Date(position).getSeconds()),
    labelPlacement: "outside"
  }
  chart.render();
 }

Please take a look at this JSFiddle for working example.
