I would like to acknowledge the entire Matplotlib development team for their insightful responses to my questions while I was writing this book. In particular, I would like to thank Michael Droettboom, Eric Firing, Thomas Caswell, Phil Elson, and Ryan May. Thanks also go to the members of the matplotlib users' list without whom I would have never learned this tool in the first place and for whom I wrote this book.

This book would not have been possible without the love and support of my wife, Margaret. She put up with far more than she should have, and for that, I am in her debt.

Last, but not least, I must acknowledge John Hunter, the creator of Matplotlib and the man who included me into the development team. Working with him and the rest of the team allowed me to mature as a programmer and scientist, and directly resulted in me attaining my current employment, thus starting my career.
