Matplotlib.axes.Axes.get_agg_filter() in Python

0 0 1 minute read

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:

# 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:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import numpy as np 
         
np.random.seed(10**7) 
zambiatek = np.random.randn(100) 
    
fig, ax = plt.subplots() 
ax.acorr(zambiatek, 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()
