缩放gglot r中x轴上刻度线之间的距离

Question

我有这样的图表。 我感兴趣的是范围（-3.5,0.5）之间的微小变化，然而，仅占据了x轴的一小部分，因此很难解释。

我尝试使用变换来记录比例以获得更好的可视化，但是，它显然不适用于负值。

那么是否有任何方法来扩展这个区域以使图形看起来更好？

码：

ggplot() + geom_line(data = Final_diction, aes(x = Final_diction[,1], y 
= Final_diction[,4])) +
xlim(-3.5,20) +
geom_vline(xintercept=c(-0.5,0.5), linetype="dashed", color = "red") +
geom_vline(xintercept=c(-0.25,0.25), linetype="dashed", color = "blue") +
theme_bw() +
theme(axis.title = element_text(size = 20)) +
theme(axis.text = element_text(size = 18))

Answer 1

像这样的东西

library(ggforce)
library(ggolot2)
ggplot(mtcars, aes(x=mpg, y=disp, group=1)) +
  geom_line() + facet_zoom(xlim = c(15, 20))

Answer 2

您可以尝试添加xlim = c(minor value, major value)选项，并使用更适合您的范围

像这样的东西：

ggplot() + geom_line(data = Final_diction, aes(x = Final_diction[,1], y 
= Final_diction[,4])) +
xlim(-3.5,20) +
geom_vline(xintercept=c(-0.5,0.5), linetype="dashed", color = "red") +
geom_vline(xintercept=c(-0.25,0.25), linetype="dashed", color = "blue") +
theme_bw() +
theme(axis.title = element_text(size = 20)) +
theme(axis.text = element_text(size = 18)) +
xlim = c(-4, 1)
