ggplot/ggridges 添加层时顺序混乱
ggplot/ggridges order of is mixed up when adding layers
我需要一些帮助。
我正在使用 ggridges
,但我遇到了下面举例说明的问题:
我得到一个错误的顺序,即 y 轴的 (1, 10, 11, 2)。我希望最后一个数字的 y 轴顺序为 (1, 2, 3, 10, 20)
代码如下:
library(ggplot2)
library(ggridges)
iris1 <- iris
iris2 <- iris
# change levels
levels(iris1$Species) <- c(1,2,10)
levels(iris2$Species) <- c(1, 3, 20)
# offset iris2 so we can see it
iris2$Sepal.Length <- iris2$Sepal.Length + 1
# PLots with correct order of y
ggplot() + geom_density_ridges(data = iris1, aes(x = Sepal.Length, y = Species))
# the addition of layers throws off the order
ggplot() +
geom_density_ridges(data = iris1, aes(x = Sepal.Length, y = Species)) +
geom_density_ridges(data = iris2, aes(x = Sepal.Length, y = Species))
根据您想要的结果,第二种选择是通过 scale_y_discrete
的 limits
参数设置顺序:
library(ggplot2)
library(ggridges)
ggplot() +
geom_density_ridges(data = iris1, aes(x = Sepal.Length, y = Species)) +
geom_density_ridges(data = iris2, aes(x = Sepal.Length, y = Species)) +
scale_y_discrete(limits = as.character(c(1, 2, 3, 10, 20)))
