R How to Convert Axis of ggplot2 Graph to Logarithm (Example Code)
This tutorial shows how to transform axis values to log in the R programming language.
Setting up the Example
data(iris) # Loading iris 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 |
data(iris) # Loading iris 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 & load ggplot2 library("ggplot2") |
install.packages("ggplot2") # Install & load ggplot2 library("ggplot2")
my_plot <- ggplot(iris, # Drawing iris data set aes(x = Petal.Length, y = Sepal.Length)) + geom_point() my_plot |
my_plot <- ggplot(iris, # Drawing iris data set aes(x = Petal.Length, y = Sepal.Length)) + geom_point() my_plot
Example: Convert X-Axis of ggplot2 Graphic to Logarithm
my_plot + # Transforming x-axis to log xlab("Petal.Length (log)") + scale_x_continuous(trans = "log") |
my_plot + # Transforming x-axis to log xlab("Petal.Length (log)") + scale_x_continuous(trans = "log")
