Benjamin Walter Keller is currently a PhD candidate at McMaster University and gained his BSc in physics with a minor in computer science from the University of Calgary in 2011. His current research involves numerical modeling of galaxy evolution over cosmological timescales. As an undergraduate at the U of C, he worked on stacking radio polarization to examine faint extragalactic sources. He also worked in the POSSUM Working Group 2 to determine the requirements for stacking applications for the Australian SKA Pathfinder (ASKAP) radio telescope. He is particularly interested in questions involving stellar feedback (supernovae, stellar winds, and so on) and its impact on galaxies and their surrounding intergalactic medium.

Mastering Matplotlib covers use cases and unusual cases that require powerful tools. With easy-to-follow examples and the high-end components of Matplotlib, this book will enable you to develop advanced and interactive plots using Python scripting and Matplotlib.
Matplotlib is a multi-platform data visualization tool built upon the NumPy and SciPy frameworks. One of Matplotlib's most important features is its ability to work well with many operating systems and graphics backends. In this book, you'll get hands-on with customizing your data plots with the help of Matplotlib. You'll start with customizing plots, making a handful of special-purpose plots, and building 3D plots. You'll explore non-trivial layouts, Pylab customization, and tile configuration. You'll be able to add text, put lines in plots, and also handle polygons, shapes, and annotations.

In this book, you'll be exploring 3D plotting, one of the best features when it comes to 3D data visualization, along with Jupyter Notebook, widgets, and creating movies for enhanced data representation. Geospatial plotting will be also be explored. Finally, you'll learn how to create interactive plots with the help of Jupyter. By the end of this book, you'll be able to construct advanced plots with additional customization techniques and 3D plot types.
This book is aimed at individuals who want to explore data visualization techniques. Basic knowledge of Matplotlib and Python is required.
Chapter 1, Heavy Customization, covers customizing Pylab and also learn about working on non-trivial layouts and the different Matplotlib configuration files.
Chapter 2, Drawing on Plots, explains how to put lines in place and add text to your plots. We will also learn about playing with polygons, shapes, and versatile annotating.

This book will teach us about advanced Matplotlib plots. It will enable you to go from data to plot to insight, in order to take raw numbers, raw information, and turn them into a visualization, which will allow us to build within our mind the actual bit of insight on how the data behaves. This will also focus on the advanced tools to derive more subtle insights from your data.
In this chapter, we will be focusing on the advanced tools of plotting so that you can really derive more subtle insights from your data. The prerequisites for this course give us a basic understanding of Python and the ability to use NumPy to work with array data.
We will learn about the following topics:
Using style sheets to customize our plot's appearance
Working with Matplotlib colors
Building multi-panel plots with complex layouts
How to configure Matplotlib to use our preferences whenever we start up a new Matplotlib session
