原文:https://www.geesforgeks.org/matplotlib-figure-figure-get_default_bbox_extra_artists-in-python/
Matplotlib 是 Python 中的一个库，是 NumPy 库的数值-数学扩展。人物模块提供了顶级的艺术家，人物，包含了所有的剧情元素。该模块用于控制所有情节元素的子情节和顶层容器的默认间距。
matplotlib.figure.figure.get_default_bbox_extra_artists()方法
matplotlib 库的 get_default_bbox_extra_artists()方法图形模块用于获取用于边界框计算的默认艺术家列表。
语法:get_default_bbox_extra_artists(self)
参数:此方法不接受任何参数。
返回:该方法返回用于边界框计算的默认艺术家列表。
下面的例子说明了 matplotlib.figure.figure.get_default_bbox_extra_artists()函数在 matplotlib.figure 中的作用:
例 1:
# ImpleIn Reviewtation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.tri as tri
import numpy as np
n_angles = 36
n_radii = 10
min_radius = 2
radii = np.linspace(min_radius, 0.95, n_radii)
angles = np.linspace(0, 2 * np.pi,
n_angles,
endpoint = False)
angles = np.repeat(angles[..., np.newaxis],
n_radii,
axis = 1)
angles[:, 1::2] += 2 * np.pi / n_angles
x = (radii * np.cos(angles)).flatten()
y = (radii * np.sin(angles)).flatten()
triang = tri.Triangulation(x, y)
triang.set_mask(np.hypot(x[triang.triangles].mean(axis = 1),
y[triang.triangles].mean(axis = 1))
< min_radius)
fig, ax = plt.subplots()
ax.triplot(triang, 'bo-', lw = 1, color = "green")
w = fig.get_default_bbox_extra_artists()
print("Value Return by get_default_bbox_extra_artists() :")
for i in w:
print(i)
fig.canvas.draw()
fig.suptitle('matplotlib.figure.Figure.get_default_bbox_extra_artists()\
function Example', fontweight ="bold")
plt.show()
输出:
Value Return by get_default_bbox_extra_artists() :
AxesSubplot(0.125, 0.11;0.775x0.77)
Line2D(_line0)
Line2D(_line1)

XAxis(80.0, 52.8)
YAxis(80.0, 52.8)
Text(0.5, 1.0, '')
Text(0.0, 1.0, '')
Text(1.0, 1.0, '')
Rectangle(xy=(0, 0), width=1, height=1, angle=0)
例 2:
# ImpleIn Reviewtation of matplotlib function
import matplotlib.pyplot as plt
fig, ax1 = plt.subplots( )
ax1.set_xscale("log")
ax1.set_yscale("log")
ax1.set_adjustable("datalim")
ax1.plot([1, 3, 34, 4, 46,
3, 7, 45, 10],
[1, 9, 27, 8, 29,
84, 78, 19, 48],
"o-",
color ="green")
ax1.set_xlim(1e-1, 1e2)
ax1.set_ylim(1, 1e2)
w = fig.get_default_bbox_extra_artists()
print("Value Return by get_default_bbox_extra_artists():")
for i in w:
print(i)
fig.canvas.draw()
fig.suptitle('matplotlib.figure.Figure.get_default_bbox_extra_artists()\
function Example', fontweight ="bold")
plt.show()
输出:
Value Return by get_default_bbox_extra_artists() :
AxesSubplot(0.125, 0.11;0.775x0.77)
