Python Data Visualization Cookbook (Second Edition)

Overview of this book

Python Data Visualization Cookbook will progress the reader from the point of installing and setting up a Python environment for data manipulation and visualization all the way to 3D animations using Python libraries. Readers will benefit from over 60 precise and reproducible recipes that will guide the reader towards a better understanding of data concepts and the building blocks for subsequent and sometimes more advanced concepts. Python Data Visualization Cookbook starts by showing how to set up matplotlib and the related libraries that are required for most parts of the book, before moving on to discuss some of the lesser-used diagrams and charts such as Gantt Charts or Sankey diagrams. Initially it uses simple plots and charts to more advanced ones, to make it easy to understand for readers. As the readers will go through the book, they will get to know about the 3D diagrams and animations. Maps are irreplaceable for displaying geo-spatial data, so this book will also show how to build them. In the last chapter, it includes explanation on how to incorporate matplotlib into different environments, such as a writing system, LaTeX, or how to create Gantt charts using Python.

Animating in matplotlib


In this recipe, we will explore how to animate our figures. Sometimes it is more descriptive to have pictures moving in animations to explain what happens if we change the values of variables. Our main library has limited but usually sufficient animation capabilities and we will explain how to use them.

Getting ready

The framework for animation is added to standard matplotlib from version 1.1 and its main class is matplotlib.animation.Animation. This class is the base class, which is to be subclassed for specific behavior, as is the case with the classes already provided: TimedAnimation, ArtistAnimation, and FuncAnimation.

Description

Animation (object)

This class wraps the creation of an animation using matplotlib. It is only a base class which should be subclassed to provide the required behavior.

TimedAnimation (Animation)

The Animation subclass supports time-based animation, drawing a new frame every *interval* milliseconds.

ArtistAnimation...
