When I make a plot using geom_density_ridges() the top most plot touches the top of the panel. How do I create a little white space there for aesthetic purposes?
library(ggplot2)
library(ggridges)
ggplot(iris, aes(x = Sepal.Length, y = Species)) +
geom_density_ridges()
>Solution :
This could be achieved by increasing the expansion of the y scale via the expand argument of scale_y_discrete:
library(ggplot2)
library(ggridges)
ggplot(iris, aes(x = Sepal.Length, y = Species)) +
geom_density_ridges() +
scale_y_discrete(expand = expansion(add = c(.3, 1.4)))
#> Picking joint bandwidth of 0.181
