Change binwidth of ggplot2 Histogram Bars in R (Example Code)
In this R tutorial you’ll learn how to modify the binwidth of the bars in a ggplot2 histogram plot.
Preparing the Example
data(iris) # Loading an example data frame head(iris) # Sepal.Length Sepal.Width Petal.Length Petal.Width Species # 1 5.1 3.5 1.4 0.2 setosa # 2 4.9 3.0 1.4 0.2 setosa # 3 4.7 3.2 1.3 0.2 setosa # 4 4.6 3.1 1.5 0.2 setosa # 5 5.0 3.6 1.4 0.2 setosa # 6 5.4 3.9 1.7 0.4 setosa |
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 package |
ggplot(iris, # Default settings aes(x = Sepal.Width)) + geom_histogram() |
Example: Manually Adjust binwidth of ggplot2 Histogram
ggplot(iris, # Adjusted binwidth aes(x = Sepal.Width)) + geom_histogram(binwidth = 0.5) |
