Set y-Axis Limits of ggplot2 Boxplot in R (Example Code)

In this tutorial, I’ll demonstrate how to set the y-axis limits of a boxplot in the R programming language.

Preparing the Example

data(iris)                     # Loading 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
install.packages("ggplot2")    # Install & load ggplot2
library("ggplot2")
my_plot <- ggplot(iris,        # Drawing a ggplot2 boxplot with default settings
                  aes(x = Species,
                      y = Sepal.Length)) +
  geom_boxplot()
my_plot

r graph figure 1 set y axis limits ggplot2 boxplot

Example: Set y-Axis Limits of ggplot2 Boxplot Manually

my_plot +                      # Specifying y-axis scales manually
  ylim(0, 10)

r graph figure 2 set y axis limits ggplot2 boxplot
