在ggplot2 ->中设置x轴限制添加另一条回归线时，x轴上的数字将消失

install.packages("ggplot2")
library(ggplot2)

data <- data.frame(x = c(1, 2, 3, 4, 5), y = c(2, 4, 6, 8, 10))

p <- ggplot(data, aes(x = x, y = y)) + xlim(1, 5)

p <- p + geom_point()

p <- p + geom_smooth(method = "lm", se = FALSE)

p <- p + scale_x_continuous(breaks = seq(1, 5, 1))
