Python Matplotlib.figure.Figure.get_tight_layout()用法及代码示例


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_tight_layout()方法

matplotlib库的get_tight_layout()方法图形模块用于检查绘图时是否调用了tight_layout。

用法: get_size_inches(self)


参数:此方法不接受任何参数。

返回:此方法返回是否调用tight_layout。

以下示例说明了matplotlib.figure中的matplotlib.figure.Figure.get_tight_layout()函数:

范例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) 
  
w = fig.get_tight_layout() 
  
ax.text(-3, -80, 
        "Value Return by get_tight_layout():" 
        + str(w), 
        fontweight ="bold") 
      
fig.canvas.draw() 
fig.suptitle('matplotlib.figure.Figure.get_tight_layout()\ 
 function Example', fontweight ="bold")  
  
plt.show()

输出:

范例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)) 
  
w = fig.get_tight_layout() 
axs.text(.7, 2.8,  
         "Value Return by get_tight_layout():" 
         + str(w), 
         fontweight ="bold") 
      
fig.canvas.draw() 
  
fig.suptitle('matplotlib.figure.Figure.get_tight_layout() \ 
function Example', fontweight ="bold")  
  
plt.show()

输出:
