Create 3D figure using matplotlib

Import Python modules

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits import mplot3d

Create a 3D canvas

fig = plt.figure()
ax = plt.axes(projection='3d')

Create a 3D spiral line

ax = plt.axes(projection='3d')

# generate some random data for a 3d spiral line
zline = np.linspace(0,15,1000)
xline = np.sin(zline)
yline = np.cos(zline)

ax.plot3D(xline, yline, zline)

Create 3D dots

ax = plt.axes(projection='3d')

zdata = 10 * np.random.random(50)
xdata = np.sin(zdata)
ydata = np.cos(zdata)

ax.scatter3D(xdata, ydata, zdata, c=zdata, cmap='Greens')
