我有多行 x 轴标签,我想在标签内向左调整(以便两条线的左侧处于相同的缩进),但位于轴刻度下方的中央。如果我使用 theme(axis.text = element_text(hjust = 0)),文本行会正确缩进到同一级别,但位于刻度线的右侧(请参阅 MWE)。我如何让它们位于刻度线下方的中央?
library(ggplot2)
library(stringr)
## Create a sample data frame
df <- data.frame(x = 1:5,
y = c(2, 4, 3, 5, 6),
label = c("Line 1 Label", "Line 2 Label is a bit longer",
"Line 3 Label is even longer than the previous one",
"Line 4 Label is not so long", "Line 5 Label"))
## Wrap the label text with str_wrap()
df$label <- str_wrap(df$label, width = 15)
## Create the plot
ggplot(df, aes(x, y)) +
geom_point() +
scale_x_continuous(breaks = 1:5, labels = df$label) +
theme(axis.text.x = element_text(hjust = 0))
