Introduction

For Python and its numerical extension NumPy, Matplotlib is a cross-platform data visualisation and graphical charting package. It provides a viable open source substitute for MATLAB. The APIs (Application Programming Interfaces) for matplotlib allow programmers to include graphs into GUI applications.

The way a Python matplotlib script is written makes it possible to create a visual data plot in the majority of cases with just a few lines of code. Two APIs are covered by the Matplotlib scripting layer:

A hierarchy of Python code objects with matplotlib at its top makes up the pyplot API. A set of OO (Object-Oriented) API items that can be put together more easily than Pyplot. Direct access to Matplotlib's backend layers is made possible using this API. People like working with Python's MatplotLib. The most popular Python library for data visualisation and exploration is matplotlib because of its unrivalled flexibility and agility. You can make a wide range of graphs and visualisations using MatplotLib. For further customization and alteration of our plots, including scatter plots and histograms, MatplotLib also provides a number of colours, themes, palettes, and other options. To create spectacular and engaging charts or to do data analysis for a machine learning project, utilise matplotlib.

Reason for popularity of matplotlib

The popularity of Matplotlib may be explained as follows:

It is basic and uncomplicated for beginners. It is open-source and completely free. Matplotlib is a comprehensive and highly configurable library. Matplotlib works well with data frames and arrays. Figures and axes are considered objects. It provides a number of stateful plotting APIs. As a consequence, techniques such as plot() can be used without specifying any arguments. Matplotlib will be familiar to those who have used MATLAB or other graph charting programmes. Matplotlib may be used in a variety of scenarios, including Python scripts, Python and iPython shells, and Jupyter Notebooks. Matplotlib is a two-dimensional plotting library. Many modifications, however, may generate complicated visualisations such as 3-D graphs, etc. It provides high-quality images and plots in a variety of formats such as png, pdf, and pgf. Controls a variety of properties of a figure, including DPI, colour, and size. Matplotlib Features

Below are some very interesting features about Matplotlib:

It is a Python data visualisation tool that is the most basic and extensively used approach for visualising data in Python. It contains tools for making publication-standard plots and figures across platforms in a variety of export formats and settings (pycharm, jupyter notebook). It also features a procedural interface called Pylab, which is designed to mimic the behaviour of MATLAB, a popular programming language among scientists and academics. MATLAB is a non-open source commercial programme. It is similar to MATLAB plotting in that it allows users total control over fonts, lines, colours, styles, and axis properties. Matplotlib with NumPy might be thought of as the open-source equivalent of MATLAB. Using Matplotlib to create high-quality static graphics for publications and professional presentations is a terrific option. It also integrates with a variety of third-party libraries and packages, allowing matplotlib's capabilities to grow. It is obvious that matplotlib, together with its multiple compatible third-party libraries, provides users with sophisticated data visualisation capabilities. Matplotlib Applications

Below mentioned are some of the common applications of matplotlib:

Matplotlib generates meaningful numbers in a variety of physical and graphical representations across several platforms. It's a Python library for usage in scripts and shells. Matplotlib may be used by web application servers. Matplotlib is a graphical user interface toolkit that may be used in a number of other graphical user interface toolkits. Graphical Representation:

INPUT:

# importing the required module

import matplotlib.pyplot as plt

# x axis values

x = [1,2,3]

# corresponding y axis values

y = [2,4,1]

# plotting the points

plt.plot(x, y)

# naming the x axis

plt.xlabel('x - axis')

# naming the y axis

plt.ylabel('y - axis')

# giving a title to my graph

plt.title('My first graph!')

# function to show the plot

plt.show()

OUTPUT:

Fig: My first graph!

For the code mentioned above, the following measures were taken:

In a list, define the x-axis and corresponding y-axis values. Use the.plot() method to plot them on canvas. Using the.xlabel() and.ylabel() methods, name the x- and y-axes. Using the.title() method, give your plot a title. Lastly, we utilise the.show() function to display your plot. Conclusion

Matplotlib's principal applications in Python include working with large amounts of data and presenting it in graphs for better comprehension. To summarise, matplotlib is an excellent programme for exploratory data analysis and showcasing publication quality. Its appeal stems from its usage of a pyplot state machine to give a simple procedural interface.
