[Solved]-highcharts data labels overlaps the plotlines value-Highcharts

Highcharts allows you to modify the position of individual data labels in the data array. In your example, you would do that like so:

data: [12.10,22.10,9.40,13.40,10.90,10.60,9.70,8.50,8.00,{y:11.90, dataLabels: {y:-8}}],

Here it is in the API: http://api.highcharts.com/highcharts#series.data.dataLabels

Although it might be best to move your plotline label underneath the line. In your example, add y:20 to plotLines[0][label].

In the API: http://api.highcharts.com/highcharts#xAxis.plotLines.label.x

As mentioned in Adam's answer you can go and postion the datalabel of the last point.

instead of data labels I advice you to position the label of the plotLine.

you can control it using the x,y position attributes and aligning it to the left

label: {
    x: -50,
    y: 10
}

This will be the best solution if your plot line will never overlap with yAxis grid lines.
