Overview of this book

In this first-of-its-kind TikZ book, you’ll embark on a journey to discover the fascinating realm of TikZ—what it’s about, the philosophy behind it, and what sets it apart from other graphics libraries. From installation procedures to the intricacies of its syntax, this comprehensive guide will help you use TikZ to create flawless graphics to captivate your audience in theses, articles, or books. You’ll learn all the details starting with drawing nodes, edges, and arrows and arranging them with perfect alignment. As you explore advanced features, you’ll gain proficiency in using colors and transparency for filling and shading, and clipping image parts. You’ll learn to define TikZ styles and work with coordinate calculations and transformations. That’s not all! You’ll work with layers, overlays, absolute positioning, and adding special decorations and take it a step further using add-on packages for drawing diagrams, charts, and plots. By the end of this TikZ book, you’ll have mastered the finer details of image creation, enabling you to achieve visually stunning graphics with great precision.

Evaluating loop variables

Let’s take a closer look at the code for Figure 10.8. Could there possibly be even more variable options to adjust? How about iterating colors and interconnecting between loop repetitions? Yes, you can achieve this within the same loop. So, let’s look at further advanced \foreach options – at first, some syntax with short examples, and then a more extended example.

Counting loop repetitions

A \foreach value list can contain alphanumeric values and patterns to be iterated through and utilized within the loop commands. However, we may want to use values based on their position in the list, such as using the (\j,0) coordinate at position j in the iterative order of list values.

This is where the count option comes into play. Let’s say we have \i as the loop variable iterating through letters. We introduce the \j counter as follows:

\foreach \i [count=\j] in {A,...,Z} {commands};

Now, while \i iterates from A to Z, \j...
