Taking a simple plot from ggplot2 manual
p <- ggplot(mtcars, aes(x = wt, y=mpg)) + geom_point()
p + geom_hline(yintercept=20)
I get a horizontal line at value 20, as advertised.
Is there a way to limit the range of this line on x axis, to let's say2 - 4 range?
You can use geom_segment()
instead of geom_hline()
and provide x=
and xend=
values you need.
p+geom_segment(aes(x=2,xend=4,y=20,yend=20))
