I downloaded the source and untarred it.
sudo python setup.py install
And below are the errors I get. By the way, Numpy is installed.

Matplotlib 2.0. x supports Python versions 2.7 through 3.10.
Since matplotlib doesn't come installed automatically with Python, you'll need to install it yourself. The easiest way to do so is by using pip, which is a package manager for Python. In most cases, this will fix the error.
Those particular errors stem from the lack of the development package for libpng.
If you use Debian/Ubuntu, try apt-get install libpng-dev first.

if you are apt-based try
$ sudo apt-get build-dep matplotlib
