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...
