Modifying the preamble to use other packages, like siunitx?

[tamasgal]

I am trying to use siunitx to format units in labels but I don't understand how to modify the preamble to include something like \usepackage{siunitx}. According to the readme, missing packages will be downloaded by the provided lightweight (Xe)LaTeX runtime so I thought this must be possible somehow.

One desperate try was this (not working):

using CairoMakie
using MakieTeX

some_label = TeXDocument(raw"""
	\documentclass{standalone}
    \usepackage{siunitx}
    \begin{document}
    $x$ / \si{\micro\meter}
    \end{document}
""")

f = Figure()
ax1 = Axis(f[1, 1], some_label)
f

That TeXDocument should be valid but I'm not sure what you were meaning to do with ax1 = Axis(f[1, 1], some_label)...

unfortunately, using MakieTeX things as x/ylabels doesn't work at the moment due to some changes in the text recipe, so you'd have to do it by creating labels and positioning them where you want them. To have a title, for example,

f = Figure()
ax1 = Axis(f[1, 1])
title = LTeX(f[0, 1], some_label; tellheight = true, tellwidth = false)

Sorry my snipped above should say xlabel=some_label

Oh okay, that's unfortunate.

Thanks for this, it's really useful to get around the problem with non-italics \mu
