Adding text annotations in seaborn

Adding texts in seaborn with the `text` function

If you want to add text to your visualizations made with seaborn you can use the text function as follows, specifying the coordinates and the text you would like to display inside the plot.

import seaborn as sns

# Plot     
ax = sns.lineplot(x = [1, 2, 3, 4, 5],
                  y = [1, 4, 2, 5, 4])

# Text annotation at x = 2, y = 1.75           
ax.text(2, 1.75, "Custom text")

Adding a text annotation in seaborn

The text can be customized in several ways. It is possible to change the style, size, color and the horizontal and vertical alignment, among other arguments, as shown in the examples below.

import seaborn as sns

# Plot     
ax = sns.lineplot(x = [1, 2, 3, 4, 5],
                  y = [1, 4, 2, 5, 4])

# Text annotation at x = 2, y = 1.75           
ax.text(2, 1.75, "Custom text", 
       fontsize = 12,          # Size
       fontstyle = "oblique",  # Style
       color = "red",          # Color
       ha = "center", # Horizontal alignment
       va = "center") # Vertical alignment

Text rotation

The rotation argument allows changing the angle of the text.

import seaborn as sns

# Plot     
ax = sns.lineplot(x = [1, 2, 3, 4, 5],
                  y = [1, 4, 2, 5, 4])

# Text annotation at x = 2, y = 1.75           
ax.text(2, 1.75, "Custom text", 
       rotation = -50)

Labelling points

Note that you can also label points, or add several texts at once if needed, using a for loop.

import seaborn as sns

x = [1, 2, 3, 4, 5]
y = [1, 4, 2, 5, 4]
texts = ["A", "B", "C", "D", "E"]

# Plot     
ax = sns.scatterplot(x = x, y = y)

for i, txt in enumerate(texts):
    ax.text(x[i], y[i], txt)
