R Add Space Between Panels of ggplot2 Facet Plot (Example Code)
This article illustrates how to increase the spacing between facet groups in a ggplot2 graphic in the R programming language.
Setting up the Example
data(iris) # Load 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) # Load 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 ggplot2 package library("ggplot2") # Load ggplot2 |
install.packages("ggplot2") # Install ggplot2 package library("ggplot2") # Load ggplot2
my_plot <- ggplot(iris, # Facet plot with default spacing aes(x = Sepal.Width, y = Sepal.Length, color = Species)) + geom_point() + facet_wrap(Species ~ .) my_plot |
my_plot <- ggplot(iris, # Facet plot with default spacing aes(x = Sepal.Width, y = Sepal.Length, color = Species)) + geom_point() + facet_wrap(Species ~ .) my_plot
Example: Add More Space Between ggplot2 Facet Panels
my_plot + # Facet plot with increased spacing theme(panel.spacing = unit(25, "mm")) |
my_plot + # Facet plot with increased spacing theme(panel.spacing = unit(25, "mm"))
