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

Matplotlib是Python中的一个库，它是 NumPy 库的数值数学扩展。它是Python中用于数组二维图的惊人可视化库，用于处理更广泛的 SciPy 堆栈。

Matplotlib.axis.Axis.get_gid()函数

matplotlib 库的轴模块中的Axis.get_gid()函数用于获取组 ID。

Syntax: Axis.get_gid(self) 
 

Parameters: This method does not accepts any parameter. 
 

Return value: This method return the group id. 

以下示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_gid()函数：

示例 1：

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np  
import matplotlib.pyplot as plt  
       
      
y, x = np.mgrid[:5, 1:6]  
    
poly_coords = [  
    (0.25, 2.75), (3.25, 2.75),  
    (2.25, 0.75), (0.25, 0.75)  
]  
      
fig, ax = plt.subplots()  
       
cells = ax.plot(x, y, x + y, color ='green')  
    
ax.add_patch(  
    plt.Polygon(poly_coords,   
                color ='forestgreen',   
                alpha = 0.5)  
    )  
    
ax.margins(x = 0.1, y = 0.05)  
ax.set_aspect('equal')  
      
for i, t in enumerate(ax.patches):  
    Axis.set_gid(t, 'patch_% d' % i) 
    print("Value Return :", Axis.get_gid(t))
            
fig.suptitle("""matplotlib.axis.Axis.get_gid()
function Example\n""", fontweight ="bold")  
    
plt.show()

输出：

Value Return : patch_ 0

示例 2：

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np  
import matplotlib.pyplot as plt  
      
       
fig, ax = plt.subplots()  
      
circle = plt.Circle((0, 0), 5, fc ='blue')  
rect = plt.Rectangle((-5, 10), 10, 5, fc ='green')  
      
ax.add_patch(circle)  
ax.add_patch(rect)  
      
circle_tip = ax.annotate('This is a blue circle.',  
            xy =(0, 0),  
            xytext =(30, -30),  
            textcoords ='offset points',  
            color ='w',  
            ha ='left',  
            bbox = dict(boxstyle ='round, pad =.5',   
                        fc =(.1, .1, .1, .92),  
                        ec =(1., 1., 1.),   
                        lw = 1,  
                        zorder = 1),  
            )  
      
rect_tip = ax.annotate('This is a green rectangle.',  
            xy =(-5, 10),  
            xytext =(30, 40),  
            textcoords ='offset points',  
            color ='w',  
            ha ='left',  
            bbox = dict(boxstyle ='round, pad =.5',  
                        fc =(.1, .1, .1, .92),   
                        ec =(1., 1., 1.),   
                        lw = 1,  
                        zorder = 1),  
            )  
    
print("Value Return :")  
for i, t in enumerate(ax.patches):  
    Axis.set_gid(t, 'patch_% d'% i) 
    print(Axis.get_gid(t))  
      
for i, t in enumerate(ax.texts):  
    Axis.set_gid(t, 'tooltip_% d'% i) 
    print(Axis.get_gid(t))  
      
ax.set_xlim(-30, 30)  
ax.set_ylim(-30, 30)  
ax.set_aspect('equal') 
            
fig.suptitle("""matplotlib.axis.Axis.get_gid()
function Example\n""", fontweight ="bold")  
    
plt.show()

输出：

Value Return :
patch_ 0
patch_ 1
tooltip_ 0
tooltip_ 1
