To plot a single point, we will use the scatter()method, and pass the three coordinates of the point. Step 3: Plot the pointĪfter we create the axes object, we can use it to create any type of plot we want in the 3D space. Note that these two steps will be common in most of the 3D plotting you do in Python using Matplotlib. We will use this axis object ‘ax’ to add any plot to the figure. We then create a 3-D axis object by calling the add_subplot method and specifying the value ‘3d’ to the projection parameter. Here we are first creating a figure of size 4 inches X 4 inches. Step 2: Create figure and axes fig = plt.figure(figsize=(4,4))Īx = fig.add_subplot(111, projection='3d') For versions 3.2.0 and higher, you can plot 3D plots without importing mpl_3D.
Note that the second import is required for Matplotlib versions before 3.2.0. It is, otherwise, not used anywhere else. The second import of the Axes3D class is required for enabling 3D projections. The first one is a standard import statement for plotting using matplotlib, which you would see for 2D plotting as well. Step 1: Import the libraries import matplotlib.pyplot as plt Let us begin by going through every step necessary to create a 3D plot in Python, with an example of plotting a point in 3D space. 3.4 Modifying the axes limits and ticks.
