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.Tick.remove_callback() Function
The Tick.remove_callback() function in axis module of matplotlib library is used to remove a callback based on its observer id.
Syntax: Tick.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.Tick.remove_callback() function in matplotlib.axis:
Example 1:
# Implementation of matplotlib function
from matplotlib.axis import Tick
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.Tick.remove_callback() \
function Example', fontweight ="bold")
plt.show()
Output:

Example 2:
# Implementation of matplotlib function
from matplotlib.axis import Tick
from random import randint, choice
import time
import matplotlib.pyplot as plt
import matplotlib.patches as patches
back_color = "black"
colors = ['red', 'green', 'blue', 'purple', "yellow", "pink"]
width, height = 4, 4
fig = plt.figure()
plt.xlim([0, width])
plt.ylim([0, height])
fig.canvas.draw()
it = 1
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.Tick.remove_callback() \
function Example', fontweight ="bold")
plt.show()
Output:
