Create Histogram with Logarithmic X-Axis in R (2 Examples)
In this tutorial you’ll learn how to display the x-axis of a graphic in logarithmic scale in the R programming language.
Preparing the Examples
data(iris) # Iris as example data 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 |
data(iris) # Iris as example data 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
Example 1: Using Base R to Create Histogram with Logarithmic X-Axis
hist(log(iris$Sepal.Length)) # Base R histogram |
hist(log(iris$Sepal.Length)) # Base R histogram
Example 2: Using ggplot2 Package to Create Histogram with Logarithmic X-Axis
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 package |
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2 package
ggplot(iris, aes(log(Sepal.Length))) + # ggplot2 histogram geom_histogram() |
ggplot(iris, aes(log(Sepal.Length))) + # ggplot2 histogram geom_histogram()
