[Solved]-How to get only whole numbers on the y-axis?-Highcharts

Can you please apply the yAxis property as min: 0. which is used to show only the positive area of Y axis.

Please apply the yAxis property as min: 0 and tickInterval: 1. which is used to show only the positive area of Y axis.

  yAxis: {
        tickInterval: 1,
        min: 0
    }

You can try using the tickInterval.

Setting tickInterval to a whole number should do the trick you require.

   yAxis: {
            tickInterval: 5
        }
