我有以下代码:
library(ggplot2)
ggplot(cars, aes(x = speed, y = dist)) +
geom_line()

其中创建了以下情节
我想要做的是将x轴(speed)值替换5,10,15,20,25为以下向量:c("-5000", "-2500", "FOO", "2500", "5000").
但为什么这会失败?
ggplot(cars, aes(x = speed, y = dist)) + geom_line() +
scale_x_discrete(labels = c("-5000", "-2500", "TSS", "2500", "5000"))

它产生了这个:
什么是正确的方法呢?
您应该使用scale_x_continuous()因为速度是一个连续变量.您还需要指定中断,即在哪里放置刻度.
ggplot(cars, aes(x = speed, y = dist)) + geom_line() +
scale_x_continuous(breaks = c(5, 10, 15, 20, 25),
labels = c("-5000", "-2500", "TSS", "2500", "5000"))
