After that, we are defining the axis of the plot where we are specifying that the plot will be of 3D projection. Parameter 2 is an array containing the points on the y-axis. Creating an Empty 3D Plot: In the below code, we will be creating an empty canvas at first. In this article, we will be learning about 3D plotting with Matplotlib. Create 3D Scatter Plot using Matplotlib and Numpy Library We can use the numpy array to create the data points and matplotlib to plot the data points in the plot. import NumPy as np import matplotlib.pyplot as plt from math import sin, cos, pi from scipy.integrate import odeint scales = np.array([1e2, 0.1, 1, 1e-15, 10, 0.1]) GM = 379312077e8 # m^3/s^2 = 9.67e7 def odes(p, t): r,x,,y,,z = p . 3D wireframe plot using the matplotlib.Axes.plot_wireframe() method. imshow(Z) pcolormesh(X, Y, Z) contour(X, Y, Z) contourf(X, Y, Z) . We can customize the arrows in various ways. Making statements based on opinion; back them up with references or personal experience. Filled contour fills the areas that were shown by the line in contour plots.
