Python Matplotlib.figure.Figure.set_tight_layout()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.set_tight_layout()方法

matplotlib庫的set_tight_layout()方法圖形模塊用於設置在繪製時是否以及如何調用tight_layout。

用法:set_tight_layout(self, tight)


參數:此方法接受下麵討論的以下參數:

  • tight:此參數包含具有鍵“pad”,“w_pad”,“h_pad”,“rect”或無的布爾值或字典。

返回值:此方法不返回任何值。

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

範例1:

# Implementation of matplotlib function  
import numpy as np 
import matplotlib.pyplot as plt 
     
      
x = np.arange(-5, 5, 0.01) 
y1 = -3*x*x + 10*x + 10
y2 = 3*x*x + x 
     
fig, ax = plt.subplots() 
fig.tight_layout() 
ax.plot(x, y1, x, y2, color='black') 
  
ax.fill_between(x, y1, y2,  
                where = y2 >y1, 
                facecolor = 'green', 
                alpha = 0.8) 
  
ax.fill_between(x, y1, y2,  
                where = y2 <= y1, 
                facecolor = 'black', 
                alpha = 0.8) 
    
fig.set_tight_layout(True) 
        
fig.canvas.draw() 
  
fig.suptitle("""matplotlib.figure.Figure.set_tight_layout() 
function Example\n\n""",fontweight="bold")  
  
plt.show() 

輸出:

範例2:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import matplotlib.tri as mtri 
import numpy as np 
      
      
# Create triangulation. 
x = np.asarray([0, 1, 2, 3, 
                0.5, 1.5, 
                2.5, 1, 2, 
                1.5]) 
  
y = np.asarray([0, 0, 0, 0, 
                1.0, 1.0, 1.0, 
                2, 2, 3.0]) 
  
triangles = [[0, 1, 4], [1, 5, 4], 
             [2, 6, 5], [4, 5, 7], 
             [5, 6, 8], [5, 8, 7],  
             [7, 8, 9], [1, 2, 5],  
             [2, 3, 6]] 
  
triang = mtri.Triangulation(x, y, triangles) 
z = np.cos(1.5 * x) * np.cos(1.5 * y) 
      
fig, axs = plt.subplots() 
  
axs.tricontourf(triang, z) 
axs.triplot(triang, 'go-', color ='white') 
fig.tight_layout(rect =(0.1, 0.1, 0.95, 0.95)) 
   
fig.set_tight_layout(False) 
       
fig.canvas.draw() 
  
fig.suptitle("""matplotlib.figure.Figure.set_tight_layout() 
function Example\n\n""", fontweight ="bold")  
  
plt.show()
