Adjust Width of Box in Boxplot using Python Matplotlib

To adjust the width of box in boxplot in Python matplotlib, we can use width in the boxplot() method.

Steps

• Set the figure size and adjust the padding between and around the subplots.
• Make a Pandas dataframe, i.e., two-dimensional, size-mutable, potentially heterogeneous tabular data.
• Make a box and whisker plot, using boxplot() method with width tuple to adjust the box in boxplot.
• To display the figure, use show() method.

Example

import pandas as pd
import numpy as np
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

data = pd.DataFrame({"Box1": np.random.rand(10), "Box2": np.random.rand(10)})
ax = plt.boxplot(data, widths=(0.25, 0.5))

plt.show()
