根据条件改变ggplot2中某些轴标签的格式 [英] Changing format of some axis labels in ggplot2 according to condition
本文介绍了根据条件改变ggplot2中某些轴标签的格式的处理方法,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
我有一个ggplot,我想根据预定义的条件只突出显示一些特定的x轴标签。
我知道轴文本是由
p> 主题(axis.text = element_text(...))
但这适用于轴的所有标签。我想要的是,格式更改只应用于条件= 1的标签。 可以包含 ifelse()
函数在元素文本()
中有不同的标签。
ggplot(iris,aes(Species,Petal.Length))+ geom_boxplot()+
theme(axis.text.x =
element_text(face = ifelse(levels(iris $ Species)==setosa,bold,italic)))
或者,您可以在 element_text()
中提供与层数相同长度的值向量。
ggplot(iris,aes(Species,Petal.Length))+ geom_boxplot()+
theme(axis.text.x = element_text(face = c(bold,斜体,粗体),
size = c(11,12,13)))
I have a ggplot and I want to highlight only some specific x-axis labels according to a predefined condition.
I know that axis text is controlled by
theme(axis.text = element_text(...))
but this applies to all labels of the axis. What I want is that the formatting change be applied only the labels that have condition = 1.
解决方案
You can include for example ifelse()
function inside element_text()
to have different labels.
ggplot(iris,aes(Species,Petal.Length))+geom_boxplot()+
theme(axis.text.x=
element_text(face=ifelse(levels(iris$Species)=="setosa","bold","italic")))
Or you can provide vector of values inside element_text()
the same length as number of levels.
ggplot(iris,aes(Species,Petal.Length))+geom_boxplot()+
theme(axis.text.x = element_text(face=c("bold","italic","bold"),
size=c(11,12,13)))
