PaymentTransaction.group_by_day(:created_at, format: "%b %d, %Y").count,discrete: true, allowDecimals: false,yAxis: {allowDecimals: false} 

Answer 1

：

data = PaymentTransaction.group_by_day(:created_at, format: "%b %d, %Y").count 
y = data.map(&:last) 
y_discrete = ((y.min.floor)..(y.max.ceil)).to_a 
options = { vAxis: { ticks: y_discrete } } 
line_chart(data, { library: options })
