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
my_plot <- ggplot(iris,        # Create ggplot2 scatterplot
                  aes(x = Petal.Width,
                      y = Petal.Length)) +
  geom_point()
my_plot

r graph figure 1 add background color ggplot2 text label r

my_plot +                      # Add text without background
  annotate("text",
           x = 1.7,
           y = 5,
           label = "I want to show this text!")

                 label = "I want to show this text!"),
             fill = "#ffdc5e")
