I figured out how to get the count of each bin from ggplot, does anyone know how to show these numbers on the plot?

g <- ggplot()+geom_histogram()
ggplot_build(g)$data[[1]]$count

  • Use `stat_bin` with `geom_text`. – Roland May 20 '14 at 19:46

You can add a stat_bin to do the calculations of counts for you, and then use those values for the labels and heights. Here's an example

set.seed(15)
dd<-data.frame(x=rnorm(100,5,2))
ggplot(dd, aes(x=x))+ geom_histogram() +
    stat_bin(aes(y=..count.., label=..count..), geom="text", vjust=-.5)

labeled histogram

    what if you only want to show those that are non-zero? – Yannick Wurm Aug 06 '18 at 23:49

    quick n' dirty way to remove zeroes: aes(y=..count.., label=ifelse(..count..==0,"",..count..) – Jinglestar Apr 08 '21 at 11:00

    Just an update for 2023 readers, using this does still work, but replace each instance of the `..count..` with `after_stat(count)`. "The dot-dot notation (`..count..`) was deprecated in ggplot2 3.4.0. i Please use `after_stat(count)` instead." – pseudorandom May 30 '23 at 19:39
