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。
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.
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:
