How to Draw Counts on Top Each Bar of ggplot2 Barchart in R (Example Code)
In this R tutorial you’ll learn how to add the frequency count on the top of each bar of a ggplot2 barchart.
Setting up the Example
data(mtcars) # Load and inspect data table(mtcars$cyl) # 4 6 8 # 11 7 14 |
install.packages("ggplot2") # Install & load ggplot2 library("ggplot2") |
Example: Plotting Barchart with Values of Each Bar
data_cyl <- as.data.frame(table(mtcars$cyl)) # Summarizing cyl variable data_cyl # Check summarized data # Var1 Freq # 1 4 11 # 2 6 7 # 3 8 14 |
ggplot(data_cyl, aes(x = Var1, y = Freq, fill = Var1)) + # Draw cyl with values on top geom_bar(stat = "identity") + geom_text(aes(label = Freq), vjust = 0) |
