Matplotlib Overview
1. Introduction to Matplotlib
What is Matplotlib: Matplotlib is a comprehensive library in Python for creating static, animated, and
interactive visualizations.
History of Matplotlib: Matplotlib was created by John D. Hunter in 2003 and has become one of the
most widely used plotting libraries in Python.
Key Features: Matplotlib provides tools for creating line plots, bar charts, scatter plots, histograms,
pie charts, and more with high customization.
2. Basic Plotting with Matplotlib
Creating a Plot: A basic plot in Matplotlib can be created using the plot() function, with x and y data
points passed as arguments.
Labels and Titles: The xlabel(), ylabel(), and title() functions are used to add axis labels and titles to
the plot.
Showing and Saving Plots: Plots can be displayed using the show() function or saved to a file with
savefig().
3. Customizing Plots
Line Styles and Colors: Matplotlib allows customizing the appearance of plots with different line
styles (e.g., dashed, dotted) and colors.
Markers: Data points can be marked with different marker styles like circles, squares, and triangles
for better visualization.
Legends: The legend() function is used to add a legend to the plot, helping identify different lines or
markers in the plot.
4. Subplots in Matplotlib
Creating Subplots: Matplotlib's subplot() function allows for creating multiple plots (subplots) within a
single figure.
Grid of Subplots: The subplots() function creates a grid of subplots, where each subplot can have its
