Grafana Graph Left Y

Created Grafana Graph with left Y is interger, The Y axe doesn’t have min or max value,
select the unit of Left Y = Short, and Scale=linear,

The Left Y show values like 3.5, 3.0 2.5, 2.0,1.0,0.5,0

how can i let grafana know the Y axe is interger type?

you cannot, it will try to add Y-axis ticks automatically
