Technical requirements

This chapter’s examples are at https://tikz.org/chapter-13. On GitHub, they are at https://github.com/PacktPublishing/LaTeX-graphics-with-TikZ/tree/main/13-plotting.

The pgfplots package is crucial here and must be installed in your LaTeX distribution. pgfplots is built on the pgf/TikZ packages, so you must have it installed and loaded in your document. If you don’t load pgf/TikZ explicitly, pgfplots will load it automatically. If you use TikZ.org, Overleaf, or TeXlive.net, pgfplots is already included. We will also use the pgfplots libraries colormaps, fillbetween, and polar, which are bundled with pgfplots.
