[Solved]-Highchart yAxis Values-Highcharts

Use tickInterval:

        yAxis: {
            min: 0,
            max: 200,

            title: {
                text: ''
            },
            tickInterval: 40,
            gridLineWidth: 1,
            gridLineColor: '#eaeaea'

        },

You can use tickPositions / tickPositioner

or set min/max values as manishie mentioned.
