Python中的 Matplotlib.artist.Artist.findobj()
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.findobj() 方法
matplotlib 库的艺术家模块中的 findobj () 方法用于返回查找艺术家对象。
Syntax: Artist.findobj(self, match=None, include_self=True)
Parameters: This method accepts the following parameters.
- match : This parameter is the filter criterion for the matches. It default value is None.
- include_self : This parameter include self in the list to be checked for a match.
Returns: This method return artists(list of Artist).
下面的示例说明了 matplotlib.artist.Artist。 matplotlib 中的findobj ()函数：
示例 1：
# Implementation of matplotlib function
from matplotlib.artist import Artist
import matplotlib.pyplot as plt
from matplotlib.lines import Line2D
import numpy as np
from numpy.random import rand
fig, ax2 = plt.subplots()
ax2.bar(range(10), rand(10), picker = True)
print("Value return : \n",
*list(Artist.findobj(ax2)), sep ="\n")
plt.title("""matplotlib.artist.Artist.findobj()
function Example""", fontweight="bold")
plt.show()
输出：
