Python 中的 Matplotlib.axis.Axis.findobj()函数

原文:https://www . geesforgeks . org/matplotlib-axis-axis-find obj-function-in-python/

Matplotlib 是 Python 中的一个库,是 NumPy 库的数值-数学扩展。这是一个神奇的 Python 可视化库,用于 2D 数组图,并用于处理更广泛的 SciPy 堆栈。

Matplotlib.axis.Axis.findobj()函数

matplotlib 库的 Axis 模块中的 Axis.findobj()函数用于查找艺术家对象。

语法: Axis.findobj(self,match=None,include_self=True)

参数:该方法接受以下参数。

  • 匹配:该参数是匹配的过滤标准。默认值为无。
  • include_self : 此参数将 self 包含在要检查匹配的列表中。

返回值:此方法返回艺术家(艺术家列表)。

下面的例子说明了 matplotlib.axis.Axis.findobj()函数在 matplotlib.axis 中的作用:

例 1:

Python 3

# Implementation of matplotlib function
from matplotlib.axis import Axis
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(Axis.findobj(ax2)), sep ="\n")

fig.suptitle("""matplotlib.axis.Axis.findobj()
function Example\n""", fontweight ="bold")  

plt.show()

输出:

Value return : 

Rectangle(xy=(-0.4, 0), width=0.8, height=0.787316, angle=0)
Rectangle(xy=(0.6, 0), width=0.8, height=0.901399, angle=0)
Rectangle(xy=(1.6, 0), width=0.8, height=0.783699, angle=0)
Rectangle(xy=(2.6, 0), width=0.8, height=0.516764, angle=0)
Rectangle(xy=(3.6, 0), width=0.8, height=0.284635, angle=0)
Rectangle(xy=(4.6, 0), width=0.8, height=0.228809, angle=0)
Rectangle(xy=(5.6, 0), width=0.8, height=0.347976, angle=0)
Rectangle(xy=(6.6, 0), width=0.8, height=0.311647, angle=0)
Rectangle(xy=(7.6, 0), width=0.8, height=0.0261189, angle=0)
