How to plot a line in Matplotlib with an interval at each data point?

To plot a line in Matplotlib with an interval at each data point, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Make an array of means and standard deviations.
Plot means using plot() method.
Fill the area between means+stds and means-stds, alpha=0.7 and color='yellow'.
To display the figure, use show() method.

Example

import numpy as np
import matplotlib.pyplot as plt

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

means = np.array([3, 5, 1, 8, 4, 6])
stds = np.array([1.3, 2.6, 0.78, 3.01, 2.32, 2.9])

plt.plot(means, color='red', lw=7)

plt.fill_between(range(6), means - stds, means + stds, alpha=.7, color='yellow')

plt.show()
