How To Show Only Integer Values On Yaxis Of Highchart?

We have a set of a data that contains counts of instances of events. These can only be integers. When we display data that has a high enough yValue the yAxis labels are integers. H

Solution 1:

Set the allowDecimals option in the y axis to false in order to prevent non integer tick marks from being displayed:

yAxis: {
    allowDecimals: false,
    labels: {
        style: {
            fontSize: '9px',
            width: '175px'
        }
    },
    title: {
        text: ''
    }
}
