μ (Mu) is very often used greek mathematical letters and has a higher repetition in probability. In this article, we are going to add μ using a command in matplotlib.

plt.text(3, 0.4, r'$\mu=100$')
#Adding μ as text
Python | Adding mu in Plot Label (1)
plt.title('Errorbar with 'r'$\mu=100$')
#Adding μ in title of the figure
Python | Adding mu in Plot Label (2)
plt.xlabel('Time ('r'$\mu=100)$')
#Adding μ in title of the figure
Python | Adding mu in Plot Label (3)
plt.ylabel('Variation ('r'$\mu=100)$')
#Adding μ in title of the figure
Python | Adding mu in Plot Label (4)

Python code for adding mu in plot label

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(0.1, 5, 0.1)
y = np.exp(-x)
yerr = 0.1 + 0.1 * np.sqrt(x)

# In text
plt.figure()
plt.errorbar(x, y, yerr=yerr)
plt.title('Errorbar')
plt.text(3, 0.4, r'$\mu=100$')
plt.show()

# In title
plt.figure()
plt.errorbar(x, y, yerr=yerr)
plt.title('Errorbar with 'r'$\mu=100$')
plt.show()

# In x-axis label
plt.figure()
plt.errorbar(x, y, yerr=yerr)
plt.xlabel('Time ('r'$\mu=100)$')
plt.show()

# In y-axis label
plt.figure()
plt.errorbar(x, y, yerr=yerr)
plt.ylabel('Variation ('r'$\mu=100)$')
plt.show()

Output:

Output is as figure
