I want to make a ggplot with 2 y-axes and control both y axes scales. I found this:

ggplot(mpg, aes(displ, hwy)) + 
  geom_point() + 
  scale_y_continuous(
    "mpg (US)", 
    sec.axis = sec_axis(~ . * 1.20, name = "mpg (UK)")
  )

I would like to control the left y-axes to limits between -20 and 110 (just an example)

Doesn't setting `limits = c(-20, 110)` do the trick? – teunbrand Jun 22 '21 at 20:11

it worked: ```ggplot(mpg, aes(displ, hwy)) + geom_point() + scale_y_continuous( "mpg (US)", limits=c(-10,200), sec.axis = sec_axis(~ . * 1.20, name = "mpg (UK)") ) ``` – user3357510 Jun 23 '21 at 07:44
