Matplotlib.axes.Axes.get_agg_filter() in Python

Last Updated : 30 Apr, 2020

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

matplotlib.axes.Axes.get_agg_filter() Function

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

Syntax: Axes.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.axes.Axes.get_agg_filter() function in matplotlib.axes: Example 1:

Python3

# Implementation of matplotlib function 
import numpy as np 
import matplotlib.pyplot as plt 
     
xx = np.random.rand(16, 30) 
     
fig, ax = plt.subplots() 
     
m = ax.pcolor(xx) 
m.set_zorder(-20)
 
w = ax.get_agg_filter()
ax.set_title("Value Return by get_agg_filter(): "+ str(w))
  
fig.suptitle('matplotlib.axes.Axes.get_agg_filter() \
function Example', fontweight ="bold") 

plt.show()

Output:

Example 2:

Python3

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
       
np.random.seed(10**7)
geeks = np.random.randn(100)
  
fig, ax = plt.subplots()
ax.acorr(geeks, usevlines = True, normed = True, 
         maxlags = 80, lw = 3)

ax.grid(True)
 
w = ax.get_agg_filter()
ax.set_title("Value Return by get_agg_filter(): "+ str(w))
  
fig.suptitle('matplotlib.axes.Axes.get_agg_filter()\
 function Example', fontweight ="bold") 

plt.show()
