Matplotlib.axis.axis.get_tightbbox()

matplotlib库的Axis模块中的Axis.get_tightbbox()函数用于获取包围轴的边框。

语法:Axis.get_tightbbox(self, renderer)

参数:该方法接受以下参数。

renderer:这个参数是RendererBase实例

返回值:该方法返回包含轴的边界框。

下面的例子演示了matplotlib.axis.axis.get_tightbbox()函数在matplotlib.axis中的作用:

示例1

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt 
import numpy as np 
    
    
X = np.arange(-10, 10, 0.5) 
Y = np.arange(-10, 10, 0.5) 
U, V = np.meshgrid(X, Y) 
      
fig, ax = plt.subplots() 
ax.quiver(X, Y, U, V) 
ax.invert_xaxis() 
w = Axis.get_tightbbox(ax.xaxis, fig.canvas.get_renderer()) 
    
print("Value Return :\n"+str(w)) 
ax.grid()
    
fig.suptitle("""matplotlib.axis.Axis.get_tightbbox()
function Example\n""", fontweight ="bold")  
        
plt.show()

输出:

Matplotlib.axis.axis.get_tightbbox()

Value Return:

Bbox(x0=75.48368298368294, y0= 29.07777777777777776, x1=574.7670454545455, y1=43.077777777777776)

xx = np.random.rand(8, 6)  
       
fig, ax = plt.subplots()  
       
m = ax.pcolor(xx)  
m.set_zorder(-2)  
w = Axis.get_tightbbox(ax.xaxis, fig.canvas.get_renderer()) 
    
print("Value Return :\n"+str(w)) 
ax.grid()
