Python Matplotlib.figure.Figure.get_default_bbox_extra_artists()用法及代碼示例

Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。 Figure模塊提供了頂層Artist,即Figure,其中包含所有繪圖元素。此模塊用於控製所有圖元的子圖和頂層容器的默認間距。

matplotlib.figure.Figure.get_default_bbox_extra_artists()方法

matplotlib庫的get_default_bbox_extra_artists()方法圖形模塊用於獲取用於邊界框計算的藝術家的默認列表。

用法: get_default_bbox_extra_artists(self)


參數:此方法不接受任何參數。

返回:此方法返回用於邊界框計算的藝術家的默認列表。

以下示例說明了matplotlib.figure中的matplotlib.figure.Figure.get_default_bbox_extra_artists()函數:

範例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()

輸出:

Value Return by get_default_bbox_extra_artists():
AxesSubplot(0.125, 0.11;0.775x0.77)
Line2D(_line0)
Line2D(_line1)
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)

範例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()

輸出:

Value Return by get_default_bbox_extra_artists():
AxesSubplot(0.125, 0.11;0.775x0.77)
Line2D(_line0)
