Matplotlib (portmanteau of MATLAB, plot, and library[3]) is a plotting library for the Python programming language and its numerical mathematics extension NumPy. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK. There is also a procedural "pylab" interface based on a state machine (like OpenGL), designed to closely resemble that of MATLAB, though its use is discouraged.[4] SciPy makes use of Matplotlib.
Matplotlib was originally written by John D. Hunter. Since then it has had an active development community[5] and is distributed under a BSD-style license. Michael Droettboom was nominated as matplotlib's lead developer shortly before John Hunter's death in August 2012[6] and was further joined by Thomas Caswell.[7][8] Matplotlib is a NumFOCUS fiscally sponsored project.[9]
Comparison with MATLAB
[edit]Pyplot is a Matplotlib module that provides a MATLAB-like interface.[10] Matplotlib is designed to be as usable as MATLAB, with the ability to use Python, and the advantage of being free and open-source.
Plot Types
[edit]Matplotlib supports various types of 2 dimensional and 3 dimensional plots. The support for two dimensional plots is robust. The support for three dimensional plots was added later and while it is good, it is not as robust as 2 dimensional plots.

Animations
[edit]Matplotlib-animation[11] capabilities are intended for visualizing how certain data changes. However, one can use the functionality in any way required.
These animations are defined as a function of frame number (or time). In other words, one defines a function that takes a frame number as input and defines/updates the matplotlib-figure based on it.
The time at the beginning of a frame-number since the start of animation can be calculated as -
Toolkits
[edit]Several toolkits are available which extend Matplotlib functionality. Some are separate downloads, others ship with the Matplotlib source code but have external dependencies.[12]
- Basemap: map plotting with various map projections, coastlines, and political boundaries[13]
- Cartopy: a mapping library featuring object-oriented map projection definitions, and arbitrary point, line, polygon and image transformation capabilities.[14] (Matplotlib v1.2 and above)
- Excel tools: utilities for exchanging data with Microsoft Excel
- GTK tools: interface to the GTK library
- Qt interface
- Mplot3d: 3-D plots
- Natgrid: interface to the natgrid library for gridding irregularly spaced data.
- tikzplotlib: export to Pgfplots for smooth integration into LaTeX documents (formerly known as matplotlib2tikz)[15]
- Seaborn: provides an API on top of Matplotlib that offers sane choices for plot style and color defaults, defines simple high-level functions for common statistical plot types, and integrates with the functionality provided by Pandas
- GeoPandas:[16] simplifies geospatial work in Python without needing a spatial database like PostGIS[17]
- Cartopy: streamlines map creation in matplotlib by enabling users to specify a projection and add coastlines with a single line of code[18]
