Change Plot Size in Matplotlib with plt.figsize()

Python | Figure Size of Plot: In this tutorial, we will learn how to change plot size in Matplotlib with plt.figsize() in Python? By Anuj Singh Last updated : August 18, 2023

Plot Figure Size

In some cases, the automatic figure size generated by the matplotlib.pyplot is not visually good or there could be some non-acceptable ratio in the figure. So, rather than allowing a pyplot to decide the figure size, we can manually define the dimensions of the figure.

Change Plot Size in Matplotlib

To change the plot/figure size of a Matplotlib plot is quite easy, you can use the plt.figsize() method which is an inbuilt method of the Matplotlib library. Consider the below-given syntax:

Syntax

matplotlib.pyplot.figure(figsize)

Example

matplotlib.pyplot.figure(figsize=(9,3))

# figsize(float, float)
    width, height in inches.

1) Wide Figure

2) Tall Plot

3) Small Square Figure

4) Square Figure

Python program for figure size of plot

# Data Visualization using Python
# Figure Size

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(50)
y = 2*x*x + 7*x - 14

# Example 1 
plt.figure(figsize=(9,5))
# Leftmost
plt.plot(x, y, 'yo')
plt.title('Plot')
plt.ylabel('Function Vaule')
plt.xlabel('x-axis')
plt.show()

# Example 2 
plt.figure(figsize=(6,9))
# Leftmost
plt.plot(x, y, 'yo')
plt.title('Plot')
plt.ylabel('Function Vaule')
plt.xlabel('x-axis')
plt.show()

# Example 3
plt.figure(figsize=(3,3))
# Leftmost
plt.plot(x, y, 'yo')
plt.title('Plot')
plt.ylabel('Function Vaule')
plt.xlabel('x-axis')
plt.show()

# Example 4 
plt.figure(figsize=(7,7))
# Leftmost
plt.plot(x, y, 'yo')
plt.title('Plot')
plt.ylabel('Function Vaule')
plt.xlabel('x-axis')
plt.show()

Output:

Output is as figure
