3D Sine Wave Using Matplotlib - Python Last Updated : 23 Jul, 2025 Comments Improve Suggest changes 1 Likes Like Report See More 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 np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D # Creating array points using numpy x = np.arange(0, 20, 0.1) y = np.sin(x) z = y*np.sin(x) c = x + y #Change the Size of Graph using Figsize fig = plt.figure(figsize = (10, 10)) #Generating a 3D sine wave ax = plt.axes(projection = '3d') # To create a scatter graph ax.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 mplot3d import numpy as np import matplotlib.pyplot as plt fig = plt.figure(figsize=(8, 8)) ax = plt.axes(projection = '3d') # Creating array points using numpy z = np.linspace(0, 15, 1000) x = np.sin(zline) y = np.cos(zline) ax.plot3D(x, y, z, 'gray') plt.show() Output: Create Quiz Comment S skrg141 Follow 1 Improve S skrg141 Follow 1 Improve Article Tags : Python Python-matplotlib Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
