Python中的 Matplotlib.axis.Tick.remove_callback()函数

Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。

matplotlib.axis.Tick.remove_callback()函数

matplotlib 库的轴模块中的Tick.remove_callback()函数用于根据其观察者 ID 删除回调。

下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Tick.remove_callback()函数:
示例 1:

Python3
# 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()


Python3
# 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()


输出:
