Here are the Code examples of this chapter. These pages are currently being updated over time (adding pictures, captions, and possibly further examples). Visit again soon for updates. Of course, the best way to use this page is together with the book for getting the explanations.

Figure 4.13 – An undesired arrow tip
Comment:
We use the arrow as edge option, because the edge operation
creates a separate path. It inherits the arrow though. But see what happens here:
\documentclass[tikz,border=10pt]{standalone}
\begin{document}
\begin{tikzpicture}
\draw[->] (0,0) edge (1,0);
\end{tikzpicture}
\end{document}
We have an undesired arrow at the beginning of the path.
Please rate (and possibly review) the book on Amazon if you got it there, your feedback means much to me and helps to get an extended second edition!
