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.

Using a smooth plot to connect points

TikZ can plot functions for us, either using a set of coordinate values or a mathematical parametrization. We will learn a lot about plotting in the next chapter; for now, let’s have just a first quick look at coordinate plots.

We will work with the set of points from the previous section. As said, we may need more points for more accuracy, so let’s look at Figure 12.2 again and choose two additional coordinates on the curve, such as two peak values (-1.3, 0.86) and (1.3, -0.86). TikZ can do a simple plot through all those points by the plot operation as follows:

\draw plot coordinates {
  (-3,-2.4) (-2,0.4) (-1.3,0.86) (-0.4,0.4)
  (0.4,-0.4) (1.3,-0.86) (2,-0.4) (3,2.4) };

These commands generate a sequence of straight linear segments:

Figure 12.5 – A plot through given coordinates

Figure 12.5 – A plot through given coordinates

That’s not smooth yet, but add the smooth keyword as an option to plot:
