Python中的 Matplotlib.artist.Artist.properties()
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.properties() 方法
matplotlib 库的艺术家模块中的properties() 方法用于获取艺术家所有属性的字典。
Syntax: Artist.properties(self)
Parameters: This method does not accepts any parameters.
Returns: This method return dictionary of all the properties of the artist.
下面的示例说明了 matplotlib 中的 matplotlib.artist.Artist.properties()函数:
示例 1:
# Implementation of matplotlib function
from matplotlib.artist import Artist
import numpy as np
import matplotlib.pyplot as plt
xx = np.random.rand(16, 30)
fig, ax = plt.subplots()
m = ax.pcolor(xx)
m.set_zorder(-20)
w = Artist.properties(ax)
print("Display all Properties\n")
for i in w:
print(i, ":", w[i])
fig.suptitle('matplotlib.artist.Artist.properties() \
function Example', fontweight ="bold")
plt.show()
