Python matplotlib.pyplot.pink()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。 Pyplot是Matplotlib模块的基于状态的接口,该模块提供了MATLAB-like接口。

matplotlib.pyplot.pink()函数:

matplotlib库的pyplot模块中的pink()函数用于将颜色映射设置为“pink”。

用法:


matplotlib.pyplot.pink()

参数:此方法不接受任何参数。

返回值:此方法不返回任何值。

以下示例说明了matplotlib.pyplot中的matplotlib.pyplot.pink()函数:

范例1:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import matplotlib.tri as tri 
import numpy as np  
         
ang = 40
rad = 10
radm = 0.35
radii = np.linspace(radm, 0.95, rad) 
         
angles = np.linspace(0, 4 * np.pi, ang) 
angles = np.repeat(angles[..., np.newaxis], rad, axis = 1) 
angles[:, 1::2] += np.pi / ang 
         
x = (radii * np.cos(angles)).flatten() 
y = (radii * np.sin(angles)).flatten() 
z = (np.sin(4 * radii) * np.cos(4 * angles)).flatten() 
         
triang = tri.Triangulation(x, y) 
triang.set_mask(np.hypot(x[triang.triangles].mean(axis = 1), 
                         y[triang.triangles].mean(axis = 1)) 
                < radm) 
         
tpc = plt.tripcolor(triang, z, shading ='flat') 
plt.pink() 
plt.title('matplotlib.pyplot.pink() function Example', fontweight ="bold") 
plt.show()

输出:

范例2:

# Implementation of matplotlib function 
import matplotlib.pyplot as plt 
import numpy as np 
from matplotlib.colors import LogNorm 
            
dx, dy = 0.015, 0.05
x = np.arange(-3.0, 3.0, dx) 
y = np.arange(-3.0, 3.0, dy) 
X, Y = np.meshgrid(x, y) 
         
extent = np.min(x), np.max(x), np.min(y), np.max(y) 
          
        
Z1 = np.add.outer(range(6), range(6)) % 2
plt.imshow(Z1, cmap ="binary_r", interpolation ='nearest', 
                 extent = extent, alpha = 1) 
         
def geeks(x, y):
    return (1 - x / 2 + x**5 + y**6) * np.exp(-(x**2 + y**2)) 
         
Z2 = geeks(X, Y) 
         
plt.imshow(Z2, alpha = 0.7, interpolation ='bilinear', 
                 extent = extent) 
plt.pink() 
plt.title('matplotlib.pyplot.pink() function Example', fontweight ="bold") 
plt.show()

输出:
