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.

Formatting the fonts

In the previous section, we saw that we can use LaTeXString objects from the LaTeXStrings package to include LaTeX equations in our plots. In this section, we will go deeper into the formatting of the different text elements of our figures. Therefore, we will learn how to customize the Font objects using the Plots package. We can create these objects using the font function. The font function takes the following keyword arguments to define the different aspects of the font:

  • family: This takes a string defining the font family. The possible values are "serif", "sans-serif", and "monospace". By default, Plots uses a sans serif font.
  • pointsize: This takes an integer defining the font size in points.
  • color: This takes a Colorant object from the Colors package or a Symbol, indicating the color name to define the color of the text.
  • halign: This defines the horizontal alignment of the text using one of the following symbols...
