'''Matplotlib''' (portmanteau of [[MATLAB]], plot, and library<ref>{{cite web | url=https://matplotlib.org/stable/project/history.html | title=History — Matplotlib 3.9.2 documentation }}</ref>) is a [[Plotter|plotting]] [[Library (computer science)|library]] for the [[Python (programming language)|Python]] [[programming language]] and its [[Numerical analysis|numerical mathematics]] extension [[NumPy]]. It provides an [[Object-oriented programming|object-oriented]] [[API]] for embedding plots into applications using general-purpose [[GUI toolkit]]s like [[Tkinter]], [[wxPython]], [[Qt (software)|Qt]], or [[GTK]]. There is also a [[Procedural programming|procedural]] "pylab" interface based on a [[state machine]] (like [[OpenGL]]), designed to closely resemble that of [[MATLAB]], though its use is discouraged.<ref>{{cite web|title=API Overview|url=https://matplotlib.org/stable/api/index.html#module-pylab|publisher=matplotlib.org}}</ref> [[SciPy]] makes use of Matplotlib.

Matplotlib was originally written by [[John D. Hunter]]. Since then it has had an active development community<ref>{{cite web |url=https://matplotlib.org/users/github_stats.html |title=Matplotlib github stats |publisher=matplotlib.org }}</ref> and is distributed under a [[BSD licenses|BSD-style license]]. Michael Droettboom was nominated as matplotlib's lead developer shortly before John Hunter's death in August 2012<ref>{{cite web |url=http://matplotlib.1069221.n5.nabble.com/ANN-Michael-Droettboom-matplotlib-lead-developer-td5037.html |title=Announcing Michael Droettboom as the lead Matplotlib developer |publisher=matplotlib.org |access-date=2013-04-24 |archive-date=2020-10-27 |archive-url=https://web.archive.org/web/20201027122844/http://matplotlib.1069221.n5.nabble.com/ANN-Michael-Droettboom-matplotlib-lead-developer-td5037.html |url-status=dead }}</ref> and was further joined by Thomas Caswell.<ref>{{Cite news|url=https://www.numfocus.org/blog/matplotlib-lead-developer-explains-why-he-cant-fix-the-docs-but-you-can|title=Matplotlib Lead Developer Explains Why He Can't Fix the Docs—But You Can – NumFOCUS|date=2017-10-05|work=NumFOCUS|access-date=2018-04-11|language=en-US}}</ref><ref>{{Cite web|url=https://matplotlib.org/users/credits.html|title=Credits – Matplotlib 2.2.2 documentation|website=matplotlib.org|access-date=2018-04-11}}</ref> Matplotlib is a [[NumFOCUS]] fiscally sponsored project.<ref>{{cite web|title=NumFOCUS Sponsored Projects|url=https://numfocus.org/sponsored-projects|publisher=NumFOCUS|access-date=2021-10-25}}</ref>

== Usage ==

Matplotlib is used in scientific research as a tool for data visualization. For example, the [[Event Horizon Telescope]] collaboration used Matplotlib to produce visualizations during the effort to create the first image of a black hole.<ref name="NumPyBlackHole">{{cite web |title=Case Study: First Image of a Black Hole |url=https://numpy.org/case-studies/blackhole-image/ |website=NumPy |access-date=22 April 2025}}</ref> Matplotlib also underpins the plotting functionality of many scientific [[Python (programming language)|Python]] libraries (for instance, [[pandas (software)|pandas]] uses Matplotlib as its default backend for plotting). Its importance to the scientific community has been acknowledged by institutions such as [[NASA]], which in 2024 awarded a grant to support Matplotlib’s continued development as part of an initiative to fund widely used open-source scientific software.<ref name="NASAOpenSource">{{cite web |title=NASA Funds Open-Source Software Underpinning Scientific Innovation |url=https://www.nasa.gov/news-release/nasa-funds-open-source-software-underpinning-scientific-innovation/ |website=NASA |access-date=22 April 2025}}</ref>

In education and data science, Matplotlib is frequently used to teach programming and data visualization. It integrates with [[Jupyter Notebook]], allowing students and instructors to generate inline plots and interactively explore data within a notebook environment.<ref name="JupyterNature">{{cite news |title=Interactive notebooks: Sharing the code |url=https://www.nature.com/articles/d41586-018-07196-1 |work=Nature |date=18 September 2018 |access-date=22 April 2025}}</ref> Many educational institutions incorporate Matplotlib into their curricula for teaching STEM concepts,<ref name="MatplotlibTutorial">{{cite web |title=Pyplot tutorial |url=https://matplotlib.org/stable/tutorials/introductory/pyplot.html |website=Matplotlib |access-date=22 April 2025}}</ref> and it is widely featured in tutorials, workshops, and open online courses as a primary plotting library.
