Matplotlib 3D Contour Plot - contour3d() Function There is a function named ax. contour3D() that is used to create a three-dimensional contour plot. This function requires all the input data to be in the form of two-dimensional regular grids, with its Z-data evaluated at each point.
How do you plot a 3D Numpy array in Python?
Putting it all together, the complete code to create a 3D scatter plot using NumPy arrays and Matplotlib looks like this:
1python.2import numpy as np.3import matplotlib.pyplot as plt.4from mpl_toolkits.mplot3d import Axes3D.5# Generate random data.6x = np.random.rand(100)7y = np.random.rand(100)8z = np.random.rand(100)
Contour plots display the 3-dimensional relationship in two dimensions, with x- and y-factors (predictors) plotted on the x- and y-scales and response values represented by contours. A contour plot is like a topographical map in which x-, y-, and z-values are plotted instead of longitude, latitude, and elevation.
