R: ggplot2 更改注释中文本周围框的边距(geom="label"...)

Question

有没有办法控制文本周围框的边距大小？

x <- data.frame(x = c(5, 10), y = c(0.5, 1))

ggplot(data=x, aes(x, y)) +
  geom_bar(stat = 'identity', fill=c("red4","cornflowerblue"))+
  annotate(geom= "label", x=5, y=.6, label="Just\ntext\nhere\nwith\ndifferent\nmargins", size=5)

Answer 1

有参数label.padding 。 请参阅文档。

ggplot(data=x, aes(x, y)) + 
  geom_bar(stat = 'identity', fill=c("red4","cornflowerblue")) + 
  annotate(geom= "label", x=5, y=.6, 
           label="Just\ntext\nhere\nwith\ndifferent\nmargins", size=5,
           label.padding=unit(4, "lines"))    # <------------
