ax = fig.add_subplot(111, projection='3d') r = np.linspace(0, 1, 100) theta = np.linspace(0, 2*np.pi, 100) r, theta = np.meshgrid(r, theta) x = r * np.cos(theta) y = r * np.sin(theta) z = r + 0.5 * x # Adding x component to make it oblique surf = ax.plot...
Here we created a basic figure with just one single graph. Now let’s try to add another. Instead of leaving the parameters forsubplots()empty, pass in two new parameters. The first argument is the number of rows, and the second is the number of columns. Passing in 2 and 1 respectivel...
