How to show the numbers on the y-axis by 1 on HighCharts?

Question

I have couple of charts working but whenever the chart spline is on 1-3 the yAxis shows numbers like 0.25, 0.75, 1.50 etc.. The spline is correct but i want to show only full numbers on the yAxis e.g 1,2,3,4,5 etc..

Any way to do that?

Answer 1

Fixed with :

allowDecimals: false
