ggplot2:如何使用geom_bar减小宽度和条之间的间隔 [英] ggplot2 : How to reduce the width AND the space between bars with geom_bar
问题描述
我知道可以使用 width
参数来更改 geom_bar
中条形的宽度。确实可行,但随后会在条之间产生更大的间隙。有没有办法手动将拉杆推得更近些?我应该以某种方式操纵轴吗?
这里是一个示例,将右侧的宽度更改为0.3以获取所需的条形宽度。
库(tidyverse)
库(gridExtra)
p1<-ggplot(iris,aes(Species,Petal) ..Length))+ geom_bar(stat = summary)
p2<-ggplot(iris,aes(Species,Petal.Length))+ geom_bar(stat = summary,width = 0.3)
grid.arrange(p1,p2,nrow = 1)
注意:我知道这个问题与此类似,但是缩小差距的答案并不明显。
I understand that one can change the width of a bar in geom_bar
using the width
argument. That does work, but then it creates a larger gap between the bars. Is there a way to manually push the bars closer to together? Should I be manipulating the axis somehow instead?
Here is an example, changing width to 0.3 on the right to get the desired bar width.
library(tidyverse)
library(gridExtra)
p1 <- ggplot(iris, aes(Species, Petal.Length)) + geom_bar(stat="summary")
p2 <- ggplot(iris, aes(Species, Petal.Length)) + geom_bar(stat="summary", width=0.3)
grid.arrange(p1,p2,nrow=1)
Note: I know this question is similar to this one, but the answer to closing the gap was not apparent.
How to change the space between bars in geom_bar?
I would adjust the plot's aspect ratio, and have ggplot
automatically assign the right width for the bars and the gap between them:
ggplot(iris, aes(Species, Petal.Length)) +
geom_bar(stat="summary", width=0.4) +
theme(aspect.ratio = 2/1)
