基本用法：

ax.scatter(xs, ys, zs, s=20, c=None, depthshade=True,?*args,?*kwargs)

• xs,ys,zs：輸入數據；
• s:scatter點的尺寸
• c:顏色，如c = 'r'就是紅色；
• depthshase:透明化，True為透明，默認為True，False為不透明
• *args等為擴展變量，如maker = 'o'，則scatter結果為’o‘的形狀

from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt import numpy as npdef randrange(n, vmin, vmax):'''Helper function to make an array of random numbers having shape (n, )with each number distributed Uniform(vmin, vmax).'''return (vmax - vmin)*np.random.rand(n) + vmin#np.random.rand(n)產生1*n數組，元素大小0-1 fig = plt.figure() ax = fig.add_subplot(111, projection='3d')n = 100# For each set of style and range settings, plot n random points in the box # defined by x in [23, 32], y in [0, 100], z in [zlow, zhigh]. for c, m, zlow, zhigh in [('r', 'o', -50, -25), ('b', '^', -30, -5)]:xs = randrange(n, 23, 32)ys = randrange(n, 0, 100)zs = randrange(n, zlow, zhigh)ax.scatter(xs, ys, zs, c=c, marker=m)ax.set_xlabel('X Label') ax.set_ylabel('Y Label') ax.set_zlabel('Z Label')plt.show()
