Y-axis display is abnormal

Description

1、I wrote a temperature curve based on the chart code. The Y-axis scale value is not displayed in the simulator, but it is normal in STM32

2、When the mouse cursor moves over the 36.6 scale value of the Y axis, it will be erased, but the 36.4 scale value will not be erased
