library(ggplot2)
library(ggridges)
ggplot(diamonds, aes(x = price, y = cut)) +
geom_density_ridges(scale = 4) + theme_ridges() +
scale_y_discrete(expand = c(0.01, 0)) + # will generally have to set the `expand` option
scale_x_continuous(expand = c(0, 0)) # for both axes to remove unneeded padding
#> Picking joint bandwidth of 458
注意x
是连续变量,y
需要切bin。
