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.

Plotting in three dimensions

pgfplots has impressive 3D plotting capabilities. There are so many customization options that we will leave most of the details to the manual and just go through a few examples here.

We will use the \addplot3 command similarly to \addplot; now, we have functions such as z = f(x,y) or parametrization in x, y, and z.

pgfplots easily provides 3D axes, drawn as a box with ticks at the edges by default. One interesting feature is color maps: we can improve our 3D visualizations by mapping the z value to a color. To get started, let’s load the corresponding library first:

\usepgfplotslibrary{colormaps}

We continue to use the radian format:

\pgfplotsset{trig format plots=rad}

We will use a black-and-white color map, where the lowest z values are black, and the higher the z value, the lighter the color. The highest z value will be printed in white.

A typical visualization is a surface plot that draws a mesh representing the function...
