Matplotlib.artist.artist.draw()

Python matplotlib库的artist模块中的draw()方法用于使用给定的渲染器绘制Artist。

语法:Artist.draw(self, renderer， *args， **kwargs)

参数:该方法接受以下参数。

renderer:这个参数是RendererBase的子类。

Returns:该方法不返回任何值。

下面的例子说明了matplotlib中的matplotlib.artist.artist.draw()函数:

示例1

# Implementation of matplotlib function
from matplotlib.artist import Artist
from mpl_toolkits.mplot3d import axes3d  
import matplotlib.pyplot as plt  
       
fig, ax = plt.subplots()  
       
def tellme(s):  
    ax.set_title(s, fontsize = 16)  
    fig.canvas.draw() 
    renderer = fig.canvas.renderer 
    Artist.draw(ax, renderer) 
     
tellme('matplotlib.artist.Artist.draw() function Example') 
ax.grid() 
  
plt.show()

输出:

Matplotlib.artist.artist.draw()

示例2

# Implementation of matplotlib function
from matplotlib.artist import Artist
from mpl_toolkits.mplot3d import axes3d  
import matplotlib.pyplot as plt  
       
    
fig = plt.figure()  
ax = fig.add_subplot(111, projection ='3d')  
       
X, Y, Z = axes3d.get_test_data(0.1)  
ax.plot_wireframe(X, Y, Z, rstride = 5,   
                  cstride = 5)  
       
for angle in range(0, 90):  
    ax.view_init(30, angle) 
    fig.canvas.draw() 
    renderer = fig.canvas.renderer 
    Artist.draw(ax, renderer)  
    plt.pause(.001) 
    
    fig.suptitle('matplotlib.artist.Artist.draw() function Example') 
ax.grid() 
  
plt.show()
