Three-dimensional Contour Plots - minifizikus - Sep-13-2018 Hi. I am beginner in Python programming. I want to do a Three-dimensional Contour Plots, like this: https://jakevdp.github.io/PythonDataScienceHandbook/04.12-three-dimensional-plotting.html . Why the code is not working? I know that "figure" is not declared in main...how can I do this? which are other mistakes in code? Can anyone write the full correct code? from matplotlib.pyplot import axis import matplotlib.pyplot as plt import numpy as np fig = plt.figure() ax = plt.axes(projection='3d') def f(x,y): return np.sin(np.sqrt(x ** 2 + y ** 2)) x = np.linspace(-6, 6, 30) y = np.linspace(-6, 6, 30) X, Y = np.meshgrid(x, y) Z = f(X, Y) fig = plt.figure() ax = plt.axes(projection='3d') ax.contour3D(X, Y, Z, 50, cmap='binary') ax.set_xlabel('x') ax.set_ylabel('y') ax.set_zlabel('z'); ax.view_init(60, 35) fig RE: Three-dimensional Contour Plots - Larz60+ - Sep-13-2018 here's a tutorial you may want to look at: https://matplotlib.org/mpl_toolkits/mplot3d/tutorial.html or this one: https://matplotlib.org/examples/mplot3d/surface3d_demo.html |
