Matplotlib.figure.Figure.set_dpi() in Python

  • Last Updated : 03 May, 2020

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The figure module provides the top-level Artist, the Figure, which contains all the plot elements. This module is used to control the default spacing of the subplots and top level container for all plot elements.

matplotlib.figure.Figure.set_dpi() method

The set_dpi() method figure module of matplotlib library is used to set the resolution of the figure in dots-per-inch.

Syntax: set_dpi(self, val)

Parameters: This method accept the following parameters that are discussed below:

  • val : This parameter is the float value.

Returns: This method does not returns any value.



Below examples illustrate the matplotlib.figure.Figure.set_dpi() function in matplotlib.figure:

Example 1:




# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
from matplotlib.figure import Figure
import numpy as np 
      
  
fig = plt.figure(figsize =(5, 4)) 
      
ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
    
xx = np.arange(0, 2 * np.pi, 0.01
ax.plot(xx, np.sin(xx)) 
   
fig.set_dpi(150.0)
    
fig.suptitle("""matplotlib.figure.Figure.set_dpi()
function Example\n\n""", fontweight ="bold") 
  
plt.show() 

Output:

Example 2:




# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
from matplotlib.figure import Figure
from mpl_toolkits.axisartist.axislines import Subplot 
import numpy as np 
  
     
fig = plt.figure(facecolor ="lightgreen"
      
ax = Subplot(fig, 111
fig.add_subplot(ax) 
      
ax.axis["left"].set_visible(False
ax.axis["top"].set_visible(False)
   
fig.set_dpi(90.0)
    
fig.suptitle("""matplotlib.figure.Figure.set_dpi()
function Example\n\n""", fontweight ="bold") 
  
plt.show() 

Output:
