Python 中的 matplotlib.artist.artist.get_animated()
原文:https://www.geesforgeks.org/matplotlib-artist-artist-get_animated-in-python/
Matplotlib 是 Python 中的一个库，是 NumPy 库的数值-数学扩展。艺术家类包含抽象基类，用于渲染到图形画布中的对象。图形中所有可见的元素都是艺术家的子类。
matplotlib.artist.artist.get_animated()方法
matplotlib 库的 artist 模块中的 get_animated()方法用于获取动画状态。
语法: Artist.get_animated(self)
参数:该方法不接受任何参数。
返回:该方法返回动画状态。
下面的例子说明了 matplotlib 中的 matplotlib.artist.artist.get_animated()函数:
例 1:
# Implementation of matplotlib function
from matplotlib.artist import Artist
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
data = np.array([[1, 2, 3, 4, 5],
[7, 4, 9, 2, 3]])
fig = plt.figure()
ax = plt.axes(xlim =(0, 20), ylim =(0, 20))
line, = ax.plot([], [], 'r-')
annotation = ax.annotate('', xy =(data[0][0],
data[1][0]))
Artist.set_animated(annotation, True)
w = Artist.get_animated(annotation)
print(str(w))
fig.suptitle('matplotlib.artist.Artist.get_animated()\
function Example', fontweight ="bold")
ax.grid()
plt.show()
输出:
True
例 2:
# Implementation of matplotlib function
from matplotlib.artist import Artist
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
fig, ax = plt.subplots()
ax.set_xlim([-1, 1])
ax.set_ylim([-1, 1])
L = 50
theta = np.linspace(0, 2 * np.pi, L)
r = np.ones_like(theta)
x = r * np.cos(theta)
y = r * np.sin(theta)
line, = ax.plot(1, 0, 'ro')
annotation = ax.annotate(
'annotation', xy =(1, 0), xytext =(-1, 0),
arrowprops = {'arrowstyle': "->"}
)
Artist.set_animated(annotation, False)
w = Artist.get_animated(annotation)
print(str(w))
fig.suptitle('matplotlib.artist.Artist.get_animated()\
function Example', fontweight ="bold")
ax.grid()
plt.show()
输出:
False
