Export with LaTeX

Make SVG visualization

If you want math equations in LaTeX, or you just want to export your visualization to LaTeX, you should follow this tutorial.

Let's start with this simple code:

import plotynium as ply

x = list(range(0, 21))
data = [
    {
        "x": xi,
        "y": pow(xi, i + 1),
        "label": (f"$y = x^{i + 1}$" if i > 0 else "$y = x$"),
    }
    for i in range(3)
    for xi in x
]

plot = ply.plot(
    marks=[ply.line(data, x="x", y="y", stroke="label")],
    color={"legend": True, "scheme": ply.Scheme.OBSERVABLE_10},
    y={"specifier": "~s"},
)

with open("figure.svg", "w") as file:
    file.write(str(plot))

Expected output

As you can see, labels contain $ in order to make math equations through LaTeX.

Convert and build your PDF

Convert the figure.svg to figure.pdf_tex with inkscape.

inkscape -D figure.svg -o figure.pdf --export-latex

Change the font size with the following command:
```
sed -i 's/\\\f@size/ 7.5/g' figure.pdf_tex
```

Create a file file.tex and add the following content:

\documentclass{article}
\usepackage{color}
\usepackage{graphicx}

\begin{document}

\begin{figure}[!ht]
  \centering
  \def\svgwidth{\columnwidth}
  \scalebox{0.8}{\input{figure.pdf_tex}}
  \caption{Cool figure}
\end{figure}

\end{document}

Compile the LaTeX file with pdflatex:
```
pdflatex file.tex
```
Open file.pdf
