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。在Pyplot中可以使用各种图，例如线图，轮廓图，直方图，散点图，3D图等。
matplotlib.pyplot.bone()函数
matplotlib库的pyplot模块中的bone()函数用于将颜色映射设置为“bone”。句法：
matplotlib.pyplot.bone()
以下示例说明了matplotlib.pyplot中的matplotlib.pyplot.bone()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, 0.5 * 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.bone()
plt.title('matplotlib.pyplot.bone() function \
Example\n\n', 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(-4.0, 4.0, dx)
y = np.arange(-4.0, 4.0, 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(8), range(8)) % 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.set_cmap("gist_rainbow")
plt.bone()
plt.title('matplotlib.pyplot.bone()\
function Example\n\n', fontweight ="bold")
plt.show()输出：
