this is because your yAxis label has decimals. You need to check if you set maximumFractionDigits to 0. non-zero means it can have decimals if possible

iI try to set
lineChart.leftAxis.valueFormatter = NSNumberFormatter()
lineChart.leftAxis.valueFormatter?.numberStyle = NSNumberFormatterStyle.NoStyle
lineChart.leftAxis.valueFormatter?.maximumFractionDigits = 0

, But have problem same that picture. TT

Can you just walk through the API and definitions by yourself first? Your set the maximumFractionDigits to 0, do you know the meaning of maximumFractionDigits?

maximumFractionDigits
 Property
The maximum number of digits after the decimal separator allowed as input and output by the receiver.
