Add Background Color to ggplot2 Text Label in R (Example Code)
In this R post you’ll learn how to add background color to a text label in a ggplot2 plot.
Preparing the Example
data(iris) # Example data in R 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, # Create ggplot2 scatterplot aes(x = Petal.Width, y = Petal.Length)) + geom_point() my_plot |
my_plot <- ggplot(iris, # Create ggplot2 scatterplot aes(x = Petal.Width, y = Petal.Length)) + geom_point() my_plot
my_plot + # Add text without background annotate("text", x = 1.7, y = 5, label = "I want to show this text!") |
my_plot + # Add text without background annotate("text", x = 1.7, y = 5, label = "I want to show this text!")
Example: Set Background Color for Text Label in ggplot2 Plot
my_plot + # Change color of text background geom_label(aes(x = 1.7, y = 5, label = "I want to show this text!"), fill = "#ffdc5e") |
my_plot + # Change color of text background geom_label(aes(x = 1.7, y = 5, label = "I want to show this text!"), fill = "#ffdc5e")
