-1501L), class = "data.frame")

The variabile: word split are letter, letters consitute words (jubal is a word, jill is a word, grocchi is a word etc.) My goal is to do a plot formatted like this...

ggplot()+geom_text(data=DF_TOT, aes(x=x, y=id_rev,label=word_split))

BUT I don't like the result because it is unreadable...due to the overlapping of the letters (e.g. Jill) I already tried to: reduce the size of letters (with more data letters are too small), paste0 \n at each letter (doesnt work), multiply by two id_rev (doesnt change because the y scale remains the same)

Do you have any idea?

Thanks a lot!

Edit: Data was updated with more data (plot refers to old data but the problem is the same)

Answer 1

You can play around position_stack():

library(ggplot2)
#Code
ggplot()+
  geom_text(data=DF_TOT,
            aes(x=x, y=id_rev,label=word_split),
            position = position_stack(0.75),size=3)

Output:

Update: In some sense this can be useful:

library(ggplot2)
library(dplyr)
#Code 2
DF_TOT %>%
  mutate(word_split=paste0(word_split,'\n ',' ')) %>%
  ggplot()+
  geom_text(aes(x=x, y=id_rev,label=word_split),
            position = position_stack(0.5),size=2)+
  scale_y_continuous(expand = c(0,0.5),limits = c(NA,90000))

Output:
