The official Matplotlib presence on the Web is made up of two web sites:
The SourceForge project page at http://sourceforge.net/projects/matplotlib/
The main web site at http://matplotlib.sourceforge.net/
The SourceForge page contains, in particular, information about the development of Matplotlib, such as the released source code tarballs and binary packages, the SVN repository location, the bug tracking system, and so on. SourceForge also hosts some mailing lists for Matplotlib which are used for developers' discussions and users support.
On the main web site, we can find several important pieces of information about the Matplotlib package itself. For example:
The official documentation for Matplotlib is extensive. It covers in detail, all the submodules and the methods exposed by them, including all of their arguments. There are too many function arguments to cover in this book, so we are presenting only the most common ones here. In case of any doubts or questions, the official documentation is a good place to start your research or to look for an answer.
We encourage you to take a look at the gallery—it's inspiring!
