原文:https://www . geesforgeks . org/matplotlib-axis-axis-set _ GID-python 中的函数/
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.set_gid()函数
matplotlib 库的 Axis 模块中的 Axis.set_gid()函数用于设置艺术家的(组)id。
语法: Axis.set_gid(self，gid)
参数:该方法接受以下参数。
- gid: 这个参数是 gid 给出的字符串。
返回值:此方法不返回值。
以下示例说明 matplotlib.axis.Axis.set_gid()函数在 matplotlib.axis: 示例 1:
Python 3
# 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)
fig.suptitle('matplotlib.axis.Axis.set_gid() \
function Example\n', fontweight ="bold")
plt.show()
输出:
例 2:
Python 3
# 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), ha ='left',
textcoords ='offset points',color ='w',
bbox = dict(boxstyle ='round, pad =.5',
fc =(.1, .1, .1, .92), ec =(1., 1., 1.),
lw = 1, zorder = 1))

xy =(-5, 10), xytext =(30, 40),color ='w',
textcoords ='offset points', ha ='left',
bbox = dict(boxstyle ='round, pad =.5',
fc =(.1, .1, .1, .92), ec =(1., 1., 1.),

for i, t in enumerate(ax.patches):
Axis.set_gid(t, 'patch_% d'% i)
for i, t in enumerate(ax.texts):
Axis.set_gid(t, 'tooltip_% d'% i)
ax.set_xlim(-30, 30)
ax.set_ylim(-30, 30)
ax.set_aspect('equal')
fig.suptitle('matplotlib.axis.Axis.set_gid() \
function Example\n', fontweight ="bold")
plt.show()
