Matplotlib.pyplot.bone() in Python Last Updated : 19 Apr, 2020 Comments Improve Suggest changes Like Article Like Report Matplotlib is a library in Python and it is numerical - mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface. There are various plots which can be used in Pyplot are Line Plot, Contour, Histogram, Scatter, 3D Plot, etc. matplotlib.pyplot.bone() Function The bone() function in pyplot module of matplotlib library is used to set the colormap to "bone". Syntax: matplotlib.pyplot.bone() Below examples illustrate the matplotlib.pyplot.bone() function in matplotlib.pyplot: Example 1: Python3 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() Output: Example 2: Python3 1== # 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() Output: Comment More infoAdvertise with us Next Article Matplotlib.pyplot.bone() in Python S SHUBHAMSINGH10 Follow Improve Article Tags : Python Python-matplotlib Practice Tags : python Similar Reads Matplotlib.pyplot.connect() in Python Matplotlib is a library in Python and it is numerical - mathematical extension for NumPy library.
