What Is Matplotlib?

Matplotlib is one of the most popular Python packages used for data visualization. It is a cross-platform library for making 2D plots from data in arrays. It provides an object-oriented API that helps in embedding plots in applications using Python GUI toolkits such as PyQt, WxPython, or Tkinter. It can be used in Python and IPython shells, Jupyter notebook and web application servers also.

Matplotlib is a Python library that is specifically designed to do effective data visualization. It’s a cornerstone of plotting libraries in Python which empowers beginners to dive into the world of attractive data visualization. Matplotlib is an open-source Python library that offers various data visualization (like Line plots, histograms, scatter plots, bar charts, Scatter plots, Pie Charts, and Area Plot etc). A beauty of the Python matplotlib library is its Python code. Its script is structured which denotes that a few lines of code are all that are required in most instances to generate a visual data plot.

Matplotlib and Pyplot

Matplotlib is a versatile toolkit that allows for the creation of static, animated, and interactive visualizations in the Python programming language.

Generally, matplotlib overlays two APIs:

• The pyplot API: to make plot using matplotlib.pyplot.
• Object-Oriented API: A group of objects assembled with greater flexibility than pyplot. It provides direct access to Matplotlib’s backend layers.

Matplotlib simplifies simple tasks and enables complex tasks to be accomplished. Following are the key aspects of matplotlib:

• Matplotlib offers to create quality plots.
• Matplotlib offers interactive figures and customizes their visual style that can be manipulated as per need.
• Matplotlib offers export to many file formats.

Online Editor

We have provided an Online Python Compiler/Interpreter. Which helps you to Edit and Execute the Python code directly from your browser. You can also execute the Matplotlib programs using this.

Try to click the icon run button to run the following matplotlib code to display a basic line plot.

Open Compiler

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 2 * np.pi, 200)
y = np.sin(x)

fig, ax = plt.subplots(figsize=(7, 4))
ax.set_title('Sin Wave')
ax.plot(x, y)
plt.show()
