javascript - Show PlotLine value on yAxis Highcharts -

-



i'm working highchart's char bar, wonder if theres way show value of average line (plot line), show value in 'yaxis' or on mouse hover show dialog exact value of plot line.

i show average line, can't read exact value on graph.

this plotlines highchart

plotlines: [{     color: 'red',     value: avg, // insert average here     width: '1',     zindex: 2 // not stuck below regular plot lines }]

enter image description here

you should able show label:

plotlines: [{     color: 'red',     value: avg, // insert average here     width: '1',     zindex: 2, // not stuck below regular plot lines     label: {         text: avg,         textalign: 'left',         x: -40     } }]
