Problem with geom_text when using position_dodge

Question

I saw this answer, but could not repeat it.

I get my data as follows:

df = data.frame(x = rep(sample(letters, 4), 2), y = round(runif(8,1,100),0), z = c(rep("group1",4), rep("group2",4))) # I then add a 'percent' column like so: df$perc[1:4] = df$y[1:4] / sum(df$y[1:4]) df$perc[5:8] = df$y[5:8] / sum(df$y[5:8]) # Which I then convert like so: df$perc = paste(round(df$perc * 100, 1), "%", sep="") # The ggplot: library(ggplot2) ggplot(df) + geom_bar(aes(z, y, fill=x), position="dodge", stat="identity") + geom_text(aes(z,y,label=perc), position=position_dodge(width=1), size=4) 

Result:

I can’t understand what I did wrong.

Answer 1

Only one minor change solves the problem. You need to specify group=x inside your geom_text(aes(...)) call.

 ggplot(df) + geom_bar(aes(z, y, fill=x), position=position_dodge(width=1), stat="identity") + geom_text(aes(z,y,label=perc, group=x), position=position_dodge(width=1), size=4)
