Get values and positions to label a ggplot histogram

geom_histogram() is just a fancy wrapper to stat_bin so you can all that yourself with the bars and text that you like. Here’s an example

#sample data
set.seed(15)
csub<-data.frame(Anomaly10y = rpois(50,5))

And then we plot it with

ggplot(csub,aes(x=Anomaly10y)) + 
    stat_bin(binwidth=1) + ylim(c(0, 12)) +  
    stat_bin(binwidth=1, geom="text", aes(label=..count..), vjust=-1.5)
