Creating and customizing Cartesian axes, ticks, and labels
In Chapter 12, Drawing Smooth Curves, we identified and plotted a few points with self-made axes and a grid. We will plot them now using pgfplots to get a first glance at the syntax.
Take a look at this code, which you can download from GitHub or the Chapter 13 page on TikZ.org:
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\begin{document}
\begin{tikzpicture}
\begin{axis}[grid]
\addplot[only marks] coordinates
{ (-3,-2.4) (-2,0.4) (-0.4,0.4)
(0.4,-0.4) (2,-0.4) (3,2.4) };
\end{axis}
\end{tikzpicture}
\end{document}
By compiling this document, we get the following output:
Figure 13.1 – Plotting coordinates
At first, we load the pgfplots package and set version 1.18 for compatibility. As pgfplots uses TikZ, every...
