How can I draw inline line labels in Matplotlib?

To draw inline labels in Matplotlib, we can use labelLines() method. −

Steps

Set the figure size and adjust the padding between and around the subplots.
Create random data points x using numpy and a list of data points, A.
Iterate the list of A, and plot X and a (iterated item) with label.
Label all the lines with their respective legends, for lines drawn.
To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt
from labellines import labelLines

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

X = np.linspace(0, 1, 500)
A = [1, 2, 5, 10, 20]

for a in A:
   plt.plot(X, np.arctan(a*X), label=str(a))

labelLines(plt.gca().get_lines(), zorder=2.5)

plt.show()
