In the following JS COde I have been trying to set the this.value of yaxis to the arrayed values of yAxisLabels but values are not being labled and chart is not dislayed accordingly.

JS CODE FOR YAXIS

var yAxisLabels = ['5','10','20','30','40','50'];


yAxis: {
    labels: {
        formatter: function () {
            for (i=0; i<=5; i++) {
                this.value=yAxisLabels[i];
                return this.value;
            }
        }
    },

    title: {
        text: 'Total fruit consumption'
    },
    stackLabels: {
        enabled: true,
        style: {
            fontWeight: 'bold',
            color: (Highcharts.theme && Highcharts.theme.textColor) || 'blue'
        }
    }
}

Answer 1

you can also set like this

tickPositions: [0, 5, 10, 20, 30, 40, 50],

Answer 2

You can use the Tick Positioner to define your axis tick values:

See jsfiddle

The important parts are:

var yAxisLabels = [0, 5, 10, 20, 30, 40, 50];

your axis label array containing numbers and not strings

and

tickPositioner: function() {
                return yAxisLabels;
            },

the tickPositioner returning your array.
