Overview of this book

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 more about tile configuration. You’ll be able to add text, put lines in plots, and also handle polygons, shapes, and annotations. Non-Cartesian and vector plots are exciting to construct, and you’ll explore them further in this book. You’ll delve into niche plots and visualize ordinal and tabular data. 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 also be explored. Finally, you’ll learn how to create interactive plots with the help of Jupyter. Learn expert techniques for effective data visualization using Matplotlib 3 and Python with our latest offering -- Matplotlib 3.0 Cookbook

Event handling with plot callbacks

This section describes how to add interactivity by capturing mouse events along with capturing keyboard clicks.

How to add interactivity by capturing mouse events

Initially, you must import everything that we normally use and use the interactive Notebook backend. Now, the user is not familiar with asynchronous programming with the callback function. This takes in an event, which is then called when that event occurs. The important information of that event is passed as an argument to that function.

We will begin by defining a function called draw_circle (event). These are the events that are passed by Matplotlib callbacks, and they include information about the event. So, in the case of a...
