Align geom_text to a geom_vline in ggplot2
ggplot2, r
Solution
Another solution for the case of one line labels would be to add a line break before/after and keep the default vjust=0.5.
ggplot(data=mtcars, aes(x=hp, y=mpg)) +
geom_point() +
theme_bw() +
geom_vline(xintercept=200, colour="grey") +
geom_text(aes(x=200, label="\nthe strong cars", y=20), colour="blue", angle=90, text=element_text(size=11)) +
geom_text(aes(x=200, label="the weak cars\n", y=20), colour="red", angle=90, text=element_text(size=11))
Problem
I used `vjust` as workaround and elaborate an acceptable distance by try and error. But this is sometimes very time consuming and changes with the font size and the axis scale. Is there a better method to align the text in the example automatic? ``` library(ggplot2) ggplot(data=mtcars, aes(x=hp, y=mpg))+ geom_point()+ theme_bw() + geom_vline(xintercept=200, colour="grey") + geom_text(aes(x=200, label="the strong cars", y=20), colour="blue", angle=90, vjust = 1.2, text=element_text(size=11))+ geom_text(aes(x=200, label="the weak cars", y=20), colour="red", angle=90, vjust = -1, text=element_text(size=11)) ggsave(filename="geomline.png", width=5.5, height=2*3, dpi=300) ```
