Matplotlib – How to show the count values on the top of a bar in a countplot?

To show the count values on the top of a bar in a countplot, we can take the following steps

Steps

Set the figure size and adjust the padding between and around the subplots.
Create a Pandas dataframe with one column.
A countplot can be thought of as a histogram across a categorical, instead of a quantitative, variable.
Iterate the returned axes of the countplot and show the count values at the top of the bars.
To display the figure, use Show() method.

Example

import seaborn as sns
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True

df = pd.DataFrame(dict(col1=np.array([2, 4, 1, 1, 1, 4])))

ax = sns.countplot(x="col1", data=df)

for p in ax.patches:
   ax.annotate('{:.1f}'.format(p.get_height()), (p.get_x()+0.25, p.get_height()+0.01))

plt.show()

Output

It will produce the following output −
