Python中的 Matplotlib.artist.Artist.get_gid()

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.get_gid() 方法

matplotlib 库的艺术家模块中的get_gid() 方法用于获取组 ID。

Syntax: Artist.get_gid(self)

Parameters: This method does not accepts any parameter.

Returns: This method return the group id.

下面的例子说明了 matplotlib 中的 matplotlib.artist.Artist.g et_gid ()函数：

示例 1：

# Implementation of matplotlib function
from matplotlib.artist import Artist 
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): 
    Artist.set_gid(t, 'patch_% d' % i)
    print("Value Return :", Artist.get_gid(t))
  
fig.suptitle("""matplotlib.artist.Artist.get_gid()
function Example""", fontweight="bold")
  
plt.show()

输出：

Value Return : patch_ 0

示例 2：

# Implementation of matplotlib function
from matplotlib.artist import Artist 
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): 
    Artist.set_gid(t, 'patch_% d'% i)
    print(Artist.get_gid(t)) 
    
for i, t in enumerate(ax.texts): 
    Artist.set_gid(t, 'tooltip_% d'% i)
    print(Artist.get_gid(t)) 
    
ax.set_xlim(-30, 30) 
ax.set_ylim(-30, 30) 
ax.set_aspect('equal') 
  
fig.suptitle("""matplotlib.artist.Artist.get_gid()
function Example""", fontweight="bold")
  
plt.show()

输出：

Value Return :
patch_ 0
patch_ 1
tooltip_ 0
tooltip_ 1
