Python中的 Matplotlib.axis.Tick.set_alpha()函数

Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。

Matplotlib.axis.Tick.set_alpha()函数

matplotlib 库的 axis 模块中的Tick.set_alpha()函数用于设置用于混合的 alpha 值。

下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Tick.set_alpha()函数:
示例 1:

Python3
# Implementation of matplotlib function
from matplotlib.axis import Tick
import matplotlib.pyplot as plt  
import numpy as np  
        
     
# create test data  
np.random.seed(10**7)  
data = [sorted(np.random.normal(0, std, 100))   
       for std in range(1, 4)]  
        
fig, ax1 = plt.subplots()  
val = ax1.violinplot(data)   
     
for i in val['bodies']:  
    i.set_facecolor('purple')  
    Tick.set_alpha(i, 0.4)
  
fig.suptitle('matplotlib.axis.Tick.set_alpha() \
function Example', fontweight ="bold")  
     
plt.show()


Python3
# Implementation of matplotlib function
from matplotlib.axis import Tick
import matplotlib.pyplot as plt  
import numpy as np  
from matplotlib.patches import Ellipse  
        
     
NUM = 100
        
ells = [Ellipse(xy = np.random.rand(2),  
                width = np.random.rand(),   
                height = np.random.rand(),  
                angle = np.random.rand() * 360)  
        for i in range(NUM)]  
        
fig, ax = plt.subplots(subplot_kw ={'aspect': 'equal'})  
       
for e in ells:  
    ax.add_artist(e)  
    e.set_clip_box(ax.bbox)   
    e.set_facecolor(np.random.rand(4))
    Tick.set_alpha(e,0.2) 
  
fig.suptitle('matplotlib.axis.Tick.set_alpha() \
function Example', fontweight ="bold")  
     
plt.show()


输出:

示例 2:

from matplotlib.patches import Ellipse  
        
     
NUM = 100

                width = np.random.rand(),   
                height = np.random.rand(),  
                angle = np.random.rand() * 360)  
        for i in range(NUM)]  
        
fig, ax = plt.subplots(subplot_kw ={'aspect': 'equal'})  
       
for e in ells:  
    ax.add_artist(e)  
    e.set_clip_box(ax.bbox)   
    e.set_facecolor(np.random.rand(4))
    Tick.set_alpha(e,0.2) 
  
fig.suptitle('matplotlib.axis.Tick.set_alpha() \
function Example', fontweight ="bold")  
     
plt.show() 

输出:
