Last Updated : 15 Jul, 2025

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. It is an amazing visualization library in Python for 2D plots of arrays and used for working with the broader SciPy stack.

Matplotlib.axis.Axis.remove_callback() Function

The Axis.remove_callback() function in axis module of matplotlib library is used to remove a callback based on its observer id.

Syntax: Axis.remove_callback(self, oid)

Parameters: This method accepts the following parameters.

oid: This parameter is the observer id.

Return value: This method does not return any value.

Below examples illustrate the matplotlib.axis.Axis.remove_callback() function in matplotlib.axis:
Example 1:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt 
import numpy as np 
import time 
  
  
def update(): 
    global timer 
    plt.get_current_fig_manager().canvas.figure.patch.set_facecolor(str(np.random.random())) 
    plt.draw() 
        
    
def start_animation(): 
    global it 
    timer = fig.canvas.new_timer(interval = 50) 
    w = timer.add_callback(update) 
    timer.start() 
    timer.remove_callback(w) 
  
it = 1
fig = plt.figure() 
start_animation() 

fig.suptitle('matplotlib.axis.Axis.remove_callback() \
function Example\n', fontweight ="bold")  
  
plt.show()

Output:

Example 2:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis

def update(): 
    global it 
    x = randint(0, width - 1)  
    y = randint(0, height - 1)  
      
    arti = patches.Rectangle(  
        (x, y), 1, 1,  
        facecolor = choice(colors),  
        edgecolor = back_color  
    )  
  
    fig.add_artist(arti) 
    fig.draw_artist(arti) 
    fig.canvas.blit(fig.bbox) 
  
    if it > 100: 
        timer.remove_callback(w) 
    it += 1
      
timer = fig.canvas.new_timer(interval = 1)  
w = timer.add_callback(update)  
timer.start()   

fig.suptitle('matplotlib.axis.Axis.remove_callback() \
function Example\n', fontweight ="bold")  
  
plt.show()
