For installation instructions and requirements, see the INSTALL file or the install documentation. If you think you may want to contribute to matplotlib, check out the guide to working with the source code.

After installation, you can launch the test suite:

py.test

Or from the Python interpreter:

import matplotlib
matplotlib.test()

Consider reading http://matplotlib.org/devel/coding_guide.html#testing for more information. Note that the test suite requires pytest and, on Python 2.7, mock. Please install with pip or your package manager of choice.

• Users mailing list: matplotlib-users@python.org
• Announcement mailing list: matplotlib-announce@python.org
• Development mailing list: matplotlib-devel@python.org
