ggplot 2 r上x轴的不同大小面

Question

以下是一种情况:

group1 <- seq(1, 10, 2)
group2 <-  seq(1, 20, 3)
x = c(group1, group2)
mydf <- data.frame (X =x , Y = rnorm (length (x),5,1), 
 groups = c(rep(1, length (group1)), rep(2, length(group2))))

ggplot(mydf, aes(X, Y, group= groups)) + geom_point()+ facet_grid (.~ group)

在下图中,不同的面由x限制缩放:

 ggplot(mydf, aes(X, Y, group= groups)) + geom_point()+ 
   facet_grid (.~ group, scales = "free_x")

由于x的总宽度有意义,我想生成不同宽度的小平面,不仅规模不同.因此,预期的方面1的宽度应该是2的一半.

Answer 1

如果我理解正确, space = "free_x"那就做你想要的.

library(ggplot2)

ggplot(mydf, aes(X, Y)) + geom_point()+ 
facet_grid (.~ groups, scales = "free_x", space = "free_x")

如果你想在x轴上采用相同的标记方式:

ggplot(mydf, aes(X, Y)) + geom_point()+ 
 scale_x_continuous(breaks = seq(0,20,2)) +
 facet_grid (.~ groups, scales = "free_x", space = "free_x")
