I tried to change y-axis scale range.  

I used the code to set the y scale: 

```
coord_cartesian(ylim = c(min(value) - 0.05, max(value) + 0.05))

```

where `value` is a numeric column.  

I want the y-axis showing from the minimum of `value` minus `0.05` to maximum of `value` plus `0.05` with the breaks of `0.05`.  

However, `coord_cartesian()` does not work. Alternatively, I tried `scale_y_continuous(breaks(min(value) - 0.05, max(value) + 0.05, 0.05))`, it does not work either. 

How to edit my code?
