R: ggplot set ylim with custom gap

I want to adjust the break (s) along the y axis of the graph. I tried two options.

option1: ylim(0.0,0.6) 
option2: scale_y_continuous(breaks=seq(0.0, 0.6, 0.1))

The problem with option 1 is that it is split every 0.2 to the limit of the y axis, which is 0.6. Example of problem1 The problem with option 2 is that it gives this illusion of a radical difference between the graphs, as it increases the 0.1 segment of the graph. Example of problem2

I want the y axis to be split every 0.1, or tune it to any gap, showing the maximum y-axix limit (in this case, from 0.0 to 0.6, but interrupt every 0.1).
