Adding a scatter of points to a boxplot using Matplotlib
To add a scatter of points to a boxplot using matplotlib, we can use boxplot() method and enumerate the Pandas dataframe to get the x and y data points to plot the scatter points.
Steps
Set the figure size and adjust the padding between and around the subplots.
Make a dataframe using DataFrame class with the keys, Box1 and Box2.
Make boxplots from the dataframe.
Find x and y for the scatter plot using data (Step 1).
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)})
data.boxplot()
for i, d in enumerate(data):
y = data[d]
x = np.random.normal(i + 1, 0.04, len(y))
plt.scatter(x, y)
plt.show()Output
