Matplotlib is a Python 2D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments across platforms. Matplotlib can be used in Python scripts, the Python and IPython shells, the Jupyter notebook, web application servers, and four graphical user interface toolkits.

Matplotlib tries to make easy things easy and hard things possible. You can generate plots, histograms, power spectra, bar charts, errorcharts, scatterplots, etc., with just a few lines of code. For examples, see the sample plots and thumbnail gallery.

For simple plotting the pyplot module provides a MATLAB-like interface, particularly when combined with IPython. For the power user, you have full control of line styles, font properties, axes properties, etc, via an object oriented interface or via a set of functions familiar to MATLAB users.

Toolkits

Matplotlib ships with several add-on toolkits, including 3d plotting with mplot3d, axes helpers in axes_grid1 and axis helpers in axisartist.

Third party packages

A large number of third party packages extend and build on Matplotlib functionality, including several higher-level plotting interfaces (seaborn, holoviews, ggplot, ...), and two projection and mapping toolkits (basemap and cartopy).

Citing Matplotlib

Matplotlib is the brainchild of John Hunter (1968-2012), who, along with its many contributors, have put an immeasurable amount of time and effort into producing a piece of software utilized by thousands of scientists worldwide.

If Matplotlib contributes to a project that leads to a scientific publication, please acknowledge this work by citing the project. A ready-made citation entry is available.
