Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Artist class contains Abstract base class for objects that render into a FigureCanvas. All visible elements in a figure are subclasses of Artist.

Matplotlib.artist.Artist.get_agg_filter() Method

The get_agg_filter() method in artist module of matplotlib library is used to get the filter function to be used for agg filter.

Syntax: Artist.get_agg_filter(self)

Parameters: This method does not accepts any parameter.

Returns: This method return filter function to be used for agg filter.

Below examples illustrate the matplotlib.artist.Artist.get_agg_filter() function in matplotlib:

Example 1:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib.artist import Artist  
  
  
xx = np.random.rand(16, 30) 
  
fig, axs = plt.subplots() 
  
m = axs.pcolor(xx) 
m.set_zorder(-20) 
  
# use of get_agg_filter() method 
val = Artist.get_agg_filter(axs) 
axs.set_title("Value Return by get_agg_filter(): "
              + str(val)) 
  
fig.suptitle('matplotlib.artist.Artist.get_agg_filter() \ 
function Example', fontweight="bold") 
  
plt.show()

Output:

Example 2:

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
from matplotlib.artist import Artist  
  
  
np.random.seed(10**7) 
zambiatek = np.random.randn(40) 
  
fig, axs = plt.subplots() 
axs.acorr(zambiatek, usevlines=True, normed=True, 
          maxlags=30, lw=2) 
  
axs.grid(True) 
  
# use of get_agg_filter() method 
val = Artist.get_agg_filter(axs) 
axs.set_title("Value Return by get_agg_filter(): " 
              + str(val)) 
  
fig.suptitle('matplotlib.artist.Artist.get_agg_filter() \ 
function Example', fontweight="bold") 
  
plt.show()
