highcharts data labels overlaps the plotlines value

Question

I have a graph with both columns and lines. I have added a average line for the line graph using plotlines.

My problem is that the data label for the line overlaps the plotline text. I have reproduced the error here (see the last data label). : http://jsfiddle.net/cs8bqumy/

Can I add some padding after the last column to correct this?

$(function () {
            $('#container').highcharts({

                    height: 400
                },

Answer 1

You can also set max value i.e as 9.3.

Answer 2

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.

here is updated fiddle
