Editor to share with you how to draw 3D graphics in python Axes3D. I hope you will get something after reading this article. Let's discuss it together.

Description

1. Axes3D, a function for drawing 3D coordinates.

Create a drawing object and use this drawing object to create an Axes object.

2. X axis-2 to 2, Y axis-2 to 2.

Draw the lattice on the plane with the points on the two axes, the square sum of X and Y and the root sign.

3. Calculate the sin function and assign it to Z coordinate.

Specific function methods can be viewed with help (function).

4. Indicate the three axes.

Example

#-*-coding: utf-8-*-# By:Eastmount CSDNfrom matplotlib import pyplot as pltimport numpy as npfrom mpl_toolkits.mplot3d import Axes3D # function for drawing 3D coordinates fig = plt.figure () # create a drawing object ax = Axes3D (fig) # create an Axes object X = np.arange (- 2,2) with this drawing object Y = np.arange (- 2,2,0.25) # Y axis-2 to 2 print (Y) X, Y = np.meshgrid (X) Y) # use points on two axes to draw the lattice R = np.sqrt (X-axis 2 + Y-axis 2) # the sum of squares of X and Y, the open root sign Z = np.sin (R) # calculate the sin function assignment to the Z coordinate # the specific function method can be viewed by help (function) For example: help (ax.plot_surface) ax.plot_surface (X, Y, Z, rstride=1, cstride=1, cmap='rainbow') # Mark the three axes ax.set_xlabel ('xlabel', color='r') ax.set_ylabel ('ylabel', color='g') ax.set_zlabel ('zlabel', color='b') plt.show () after reading this article, I believe you have some understanding of "how python Axes3D draws 3D graphics" If you want to know more related knowledge, welcome to follow the industry information channel, thank you for reading!
