Matplotlib是Python中的一个库,它是数字的-NumPy库的数学扩展。 Figure模块提供了顶层Artist,即Figure,其中包含所有绘图元素。此模块用于控制所有图元的子图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艺术家的默认列表。
用法: get_default_bbox_extra_artists(self)
参数:此方法不接受任何参数。
返回:此方法返回用于边界框计算的艺术家的默认列表。
以下示例说明了matplotlib.figure中的matplotlib.figure.Figure.get_default_bbox_extra_artists()函数:
范例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) Spine Spine Spine Spine 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)
范例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) Line2D(_line0) Spine Spine Spine Spine 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)
