Introduction to Matplotlib (original) (raw)

Last Updated : 18 Feb, 2025

Matplotlib is a powerful and versatile open-source plotting library for Python, designed to help users visualize data in a variety of formats. Developed by John D. Hunter in 2003, it enables users to graphically represent data, facilitating easier analysis and understanding. If you want to convert your boring data into interactive plots and graphs, Matplotlib is the tool for you.

To learn Matplotlib from scratch to detail, refer to our article: Matplotlib Tutorial.

**Example of a Plot in Matplotlib:

Let's create a simple line plot using Matplotlib, showcasing the ease with which you can visualize data.

Python `

import matplotlib.pyplot as plt

x = [0, 1, 2, 3, 4] y = [0, 1, 4, 9, 16]

plt.plot(x, y) plt.show()

`

The parts of a Matplotlib figure include (as shown in the figure above):

Matplotlib Pyplot

Pyplot is a module within Matplotlib that provides a MATLAB-like interface for making plots. It simplifies the process of adding plot elements such as lines, images, and text to the axes of the current figure. **Steps to Use Pyplot:

Let's visualize a basic plot, and understand basic components of matplotlib figure:

Python `

import matplotlib.pyplot as plt

x = [0, 2, 4, 6, 8] y = [0, 4, 16, 36, 64]

fig, ax = plt.subplots()
ax.plot(x, y, marker='o', label="Data Points")

ax.set_title("Basic Components of Matplotlib Figure") ax.set_xlabel("X-Axis") ax.set_ylabel("Y-Axis")

plt.show()

`
