3D Sine Wave Using Matplotlib – Python
Prerequisites: Mathplotlib, NumPy
In the Cartesian coordinate system, the trigonometric sine function sin(x) sin (x) generates a regular undulating curve, which passes through the origin. Its values range between −1 − 1 and 1 1 for all real values of x x.
In this article, we will plot a sin wave graph using scatter in 3-Dimension. A simple way to plot sine wave in python using matplotlib.
Approach:
- Import required libraries.
- Create an array of points.
- Plotting 3D-graph.
- Create a sin wave.
- Show Graph.
Example 1: In this example, we are plotting a 3-d graph of the sine wave signal using the scatter method.
Python3
import numpy as npimport matplotlib.pyplot as pltfrom mpl_toolkits.mplot3d import Axes3D # Creating array points using numpyx = np.arange(0, 20, 0.1)y = np.sin(x)z = y*np.sin(x)c = x + y #Change the Size of Graph using Figsizefig = plt.figure(figsize = (10, 10)) #Generating a 3D sine waveax = plt.axes(projection = '3d') # To create a scatter graphax.scatter(x, y, z, c = c) # show the graph plt.show() |
Output:
Example 2: In this example, we are plotting a simple 3-D line graph of the sine wave signal.
Python3
from mpl_toolkits import mplot3dimport numpy as npimport matplotlib.pyplot as plt fig = plt.figure(figsize=(8, 8))ax = plt.axes(projection = '3d') # Creating array points using numpyz = np.linspace(0, 15, 1000)x = np.sin(zline)y = np.cos(zline)ax.plot3D(x, y, z, 'gray') plt.show() |
