Matplotlib.artist.Artist.properties() in Python
原文：https://www.geeksforgeeks.org/matplotlib-artist-artist-properties-in-python/
Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Artist class contains Abstract base class for objects that render into a FigureCanvas. All visible elements in a figure are subclasses of Artist.
matplotlib.artist.Artist.properties() method
The properties() method in artist module of matplotlib library is used to get the dictionary of all the properties of the artist.
Syntax: Artist.properties(self)
Parameters: This method does not accepts any parameters.Returns: This method return dictionary of all the properties of the artist.
Below examples illustrate the matplotlib.artist.Artist.properties() function in matplotlib:
Example 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()
Output:
