What is MatplotLib? 

Introduction

Matplotlib is a library in Python Programming Language, which provides an object-oriented API for embedding plots into applications using general-purpose  GUI toolkits like Tkinter, wxPython, Qt or GTK+. It was originally written by John D.Hunter.

Installation

python -mpip install -U matplotlib

Importing Matplotlib

from matplotlib import pyplot as plt
or
import matplotlib.pyplot as plt

Performing Line Plot

# importing matplotlib module  
from matplotlib import pyplot as plt 
  
# x-axis values 
x = [5, 2, 9, 4, 7] 
  
# Y-axis values 
y = [10, 5, 8, 4, 2] 
  
# Function to plot 
plt.plot(x,y) 
  
# function to show the plot 
plt.show() 

Performing Bar Plot

# importing matplotlib module  
from matplotlib import pyplot as plt 
  
# x-axis values 
x = [5,8,6,1,3] 
  
# Y-axis values 
y = [3,5,9,7,6] 
  
# Function to plot 
plt.bar(x,y) 
  
# function to show the plot 
plt.show() 

Performing Scatter Plot

# importing matplotlib module  
from matplotlib import pyplot as plt 
  
# x-axis values 
x = [5,8,6,1,3] 
  
# Y-axis values 
y = [3,5,9,7,6] 
  
# Function to plot 
plt.scatter(x,y) 
  
# function to show the plot 
plt.show() 

Performing Histogram 

# importing matplotlib module  
from matplotlib import pyplot as plt 
  
# Y-axis values 
y = [15,6,8,6,22] 
  
# Function to plot histogram 
plt.hist(y) 
  
# Function to show the plot 
plt.show()
