Python中的 matplotlib.pyplot.plasma()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 Pyplot是Matplotlib模块的基于状态的接口,它提供了一个类似 MATLAB 的接口。
matplotlib.pyplot.plasma()函数:
matplotlib 库的 pyplot 模块中的plasma()函数用于将颜色图设置为“plasma”。
Syntax:
Parameters: This method does not accepts any parameters.
Return value: This method does not returns any value.

# 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.plasma()
plt.title('matplotlib.pyplot.plasma() function Example', fontweight ="bold")
plt.show()
输出:
