You can add one to the X-axis and Y-axis scale

scales: {
    yAxes: [{
        ticks: {
            max: 5,
            min: 0,
            stepSize: 1
        }
    }]
}

In the option max you choose the maximum scale value, in the min the minimum value, in stepSize is how much your scale will increase, in your case: 1.

EDIT: You don’t need to pass the amount min and max if you don’t want it, it’s just information.

You can find more information here http://www.chartjs.org/docs/latest/axes/cartesian/linear.html#step-size

I hope I’ve helped!
