将整个文本放入 plot 区域

Question

I want to create a plot with text but it seems that ggplot ignores text when identifying x and y limits (it uses only centerpoint). So if the text too long it is not fully visible.

df <- tibble(x = 1:5, y = 1:5)
ggplot(df, aes(x, y, label = paste(rep("long text", 3), collapse = " "))) +
  geom_point() + geom_text(nudge_y = 0.2)

In this case one can add layer expand_limits(x = c(0.4, 5.6)) but that doesn't work for any other case. I would like to have something that works for any values of x and y and any length of text.

Answer 1

You can use ggrepel for this:

library(ggrepel)

ggplot(df, aes(x, y, label = paste(rep("long text", 3), collapse = " "))) +
  geom_point() + ggrepel::geom_text_repel(nudge_y = 0.2, segment.alpha = 0)
