Interactive Visualization and Plotting with Julia

By: Diego Javier Zea

Overview of this book

The Julia programming language offers a fresh perspective into the data visualization field. Interactive Visualization and Plotting with Julia begins by introducing the Julia language and the Plots package. The book then gives a quick overview of the Julia plotting ecosystem to help you choose the best library for your task. In particular, you will discover the many ways to create interactive visualizations with its packages. You’ll also leverage Pluto notebooks to gain interactivity and use them intensively through this book. You’ll find out how to create animations, a handy skill for communication and teaching. Then, the book shows how to solve data analysis problems using DataFrames and various plotting packages based on the grammar of graphics. Furthermore, you’ll discover how to create the most common statistical plots for data exploration. Also, you’ll learn to visualize geographically distributed data, graphs and networks, and biological data. Lastly, this book will go deeper into plot customizations with Plots, Makie, and Gadfly—focusing on the former—teaching you to create plot themes, arrange multiple plots into a single figure, and build new plot types. By the end of this Julia book, you’ll be able to create interactive and publication-quality static plots for data analysis and exploration tasks using Julia.

Customizing the axes

In the previous section, we saw how to customize the text elements of the axes. In this section, we will learn about the Plots attributes to customize other aspects of the axes, except those determining the colors, as we will discuss them later in this chapter. Look at the Axis type documentation to gain insight into the Makie attributes to customize 2D axes.

All the Plots attributes we mention in this section modify all axes simultaneously. You need to use the x, y, or z prefix to alter the attribute of a particular axis. For example, scale=:log10 will make all axes have a logarithmic scale, while xscale=:log10 will set such a scale only for the x axis. Among the attributes specifying the axis aspects, we can find the following:

  • scale: By default, Plots sets this attribute to :identity, to use the standard linear scale. Then, depending on the backend, other scales are supported. To use a logarithmic scale, you can choose from :ln, :log2, and :log10...
