Python中的 Matplotlib.artist.Artist.set_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.set_gid() 方法

matplotlib 库的艺术家模块中的set_gid() 方法用于设置艺术家的（组）id。

Syntax: Artist.set_gid(self, gid)

Parameters: This method accepts only one parameters.

gid: This parameter is the string given as gid.

Returns: This method does not return any value.

编程需要懂一点英语

下面的示例说明了 matplotlib.artist.Artist。 matplotlib 中的set_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)
  
fig.suptitle("""matplotlib.artist.Artist.set_gid()
function Example""", fontweight="bold")
  
plt.show()

输出：
