在ggplot 2 r上与x轴成比例的不同大小的面 [英] different size facets proportional of x axis on ggplot 2 r
本文介绍了在ggplot 2 r上与x轴成比例的不同大小的面的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
以下情况:
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)
限制在下面的图中:
ggplot(mydf,aes(X,Y,group = groups))+ geom_point()+
facet_grid(。〜group,scales =free_x)
有意义,我想生产不同宽度的刻面,不仅规模不同。因此,预期方面1的宽度应该是2的一半。
b$ b
space =free_x
library(ggplot2)

ggplot (mydf,aes(X,Y))+ geom_point()+
facet_grid(。〜groups,scales =free_x,space =free_x)
如果您想在x轴上使用相同样式的标签:
ggplot (mydf,aes(X,Y))+ geom_point()+
scale_x_continuous(breaks = seq(0,20,2))+
facet_grid(。〜groups,scales =free_x,space =free_x)
The following is a situation:
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)
Different facets are scaled by x limits in the following plot:
ggplot(mydf, aes(X, Y, group= groups)) + geom_point()+ facet_grid (.~ group, scales = "free_x")
As total width of x has meaning, I want to produce facets of different width not only different scale. Thus the expected facet 1's wideth should be half the size of 2.
解决方案If I understand you correctly,
space = "free_x"
does what you want.library(ggplot2) ggplot(mydf, aes(X, Y)) + geom_point()+ facet_grid (.~ groups, scales = "free_x", space = "free_x")
And if you want the same style of labelling on the x axes:
ggplot(mydf, aes(X, Y)) + geom_point()+ scale_x_continuous(breaks = seq(0,20,2)) + facet_grid (.~ groups, scales = "free_x", space = "free_x")
