Python中的 Matplotlib.artist.Artist.get_animated()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 Artist 类包含呈现为 FigureCanvas 的对象的 Abstract 基类。图中所有可见元素都是 Artist 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。
Syntax: Artist.get_animated(self)
Parameters: This method does not accepts any parameter.
Returns: This method return the the animated state.
下面的示例说明了 matplotlib 中的 matplotlib.artist.Artist.get_animated()函数:
示例 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
示例 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
