Python | Adding Lowercase/Uppercase Gamma in Plot Label

Here, we are going to learn how to add lowercase/uppercase gamma in Python plot label?

𝛾 (lowercase gamma) and 𝝘 (uppercase gamma) are very often used greek mathematical letters. They are mostly used in physics and chemistry and other mathematical expressions, when there is topic related change (for example energy change, radioactive material) and therefore, they have registered importance in languages.

Therefore, matplotlib has defined a command for 𝛾/𝝘 usage.

In this article, we are going to add 𝛾/𝝘 using a command in matplotlib.

1) Lowercase gamma

plt.text(3, 0.4, r'$\gamma=100$')
#Adding 𝛾 as text

plt.title('Lowercase gamma 'r'$\gamma=100$')
#Adding 𝛾 in title of the figure

plt.xlabel('Lowercase gamma ('r'$\gamma=100)$')
#Adding 𝛾 in x axis label of the figure

plt.ylabel('Lowercase gamma ('r'$\gamma=100)$')
#Adding 𝛾 in y axis label of the figure

2) Uppercase Gamma

plt.text(3, 0.4, r'$\Gamma=100$')
#Adding 𝝘 as text

plt.title('Uppercase Gamma 'r'$\Gamma=100$')
#Adding 𝝘 in title of the figure

plt.xlabel('uppercase Gamma ('r'$\Gamma=100)$')
#Adding 𝝘 in x axis label of the figure

plt.ylabel('uppercase Gamma ('r'$\Gamma=100)$')
#Adding 𝝘 in y axis label of the figure

Python code for adding lowercase/uppercase gamma in python plot label

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(10)
y = np.sin(x)*np.exp(x/5)

#Lowercase gamma
#In text
plt.figure()
plt.bar(x,y, color=  'orange')
plt.title('Lowercase gamma')
plt.text(4, 5, r'$\gamma=100$')
  
plt.show()

#In title
plt.figure()
plt.bar(x,y, color=  'orange')
plt.title('Lowercase gamma 'r'$\gamma=100$')
  
plt.show()

#In x-axis label
plt.figure()
plt.bar(x,y, color=  'orange')
plt.xlabel('Lowercase gamma ('r'$\gamma=100)$')
  
plt.show()

#In y-axis label
plt.figure()
plt.bar(x,y, color=  'orange')
plt.ylabel('Lowercase gamma ('r'$\gamma=100)$')
  
plt.show()


#Uppercase Gamma
#In text
plt.figure()
plt.bar(x,y, color=  'orange')
plt.title('uppercase Gamma')
plt.text(4, 5, r'$\Gamma=100$')
  
plt.show()

#In title
plt.figure()
plt.bar(x,y, color=  'orange')
plt.title('uppercase Gamma 'r'$\Gamma=100$')
  
plt.show()

#In x-axis label
plt.figure()
plt.bar(x,y, color=  'orange')
plt.xlabel('uppercase Gamma ('r'$\Gamma=100)$')
  
plt.show()

#In y-axis label
plt.figure()
plt.bar(x,y, color=  'orange')
plt.ylabel('uppercase Gamma ('r'$\Gamma=100)$')
  
plt.show()

Output:

Output is as figure
