tok*_*ami 1 graphics label r ggplot2 geom-text
我想创建一个带有标签而不是点的 ggplot 图,但它们相互重叠,因此您无法阅读它们。有没有一种很好的方法可以自动移动它们,使其不会相互覆盖?
df = data.frame(x = c(1,4,5,6,6,7,8,8,9,1), y = c(1,1,2,5,5,5,3,5,6,4),
label = rep(c("long_label","very_long_label"),5))
ggplot(data=df) + geom_text(data=df,aes(x=x, y=y, label = label))

谢谢
ggrepel
(昨天发布到 CRAN - 2016 年 1 月 9 日)似乎是为这些情况量身定制的。但请注意:ggrepel
需要ggplot2
v2.0.0
df = data.frame(x = c(1,4,5,6,6,7,8,8,9,1), y = c(1,1,2,5,5,5,3,5,6,4),
label = rep(c("long_label","very_long_label"),5))
library(ggplot2)
library(ggrepel)
# Without ggrepel
ggplot(data = df) +
geom_text(aes(x = x, y = y, label = label))
# With ggrepel
ggplot(data = df) +
geom_text_repel(aes(x = x, y = y, label = label),
box.padding = unit(0.1, "lines"), force = 2,
segment.color = NA)
