Python matplotlib.pyplot.inferno()用法及代碼示例


Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。 Pyplot是Matplotlib模塊的基於狀態的接口,該模塊提供了MATLAB-like接口。

matplotlib.pyplot.inferno()函數:

matplotlib庫的pyplot模塊中的inferno()函數用於將顏色映射設置為“inferno”。

用法: matplotlib.pyplot.inferno()


參數:此方法不接受任何參數。

返回:此方法不返回任何值。

以下示例說明了matplotlib.pyplot中的matplotlib.pyplot.inferno()函數:

範例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.colorbar(tpc) 
plt.inferno() 
plt.title('matplotlib.pyplot.inferno() function Example',  
                                      fontweight ="bold") 
plt.show()

輸出:

範例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.inferno() 
plt.title('matplotlib.pyplot.inferno() function Example', 
                                      fontweight ="bold") 
  
plt.show()

輸出:
