如何显示所有箱形图标签 [英] How do I show all boxplot labels

问题描述

我创建了一个箱形图，左边的数据是连续变量，右边的数据有大约10个唯一选项.创建箱线图时，看不到标签.如何使它显示所有标签，可能垂直显示?

I've created a box plot, the data on the left is the continous variable and the data on the right has about 10 unique options. When I create the boxplot I cannot see the labels. How do I make it show all the labels, possibly vertically?

boxplot(data$Rate ~ as.factor(data$Purpose))

我环顾四周，无法确定我要遵循的目标.

I've looked around and cannot work out what im trying to follow.

推荐答案

您可以将参数 las = 2 添加到函数 boxplot()中，以使所有标签垂直于轴

You can add argument las=2 to function boxplot() to make all labels perpendicular to axis.

df<-data.frame(Rate=rnorm(100),Purpose=rep(letters[1:10],each=10))
boxplot(df$Rate~df$Purpose,las=2)

如果标签名称很长，则还应调整打印边距.

If your label names are long then you should adjust also plot margins.

par(mar=c(7,5,1,1))
boxplot(df$Rate~df$Purpose,las=2)
