Available LaTeX fonts

[RpfR2000]

Is there any way to use other fonts offered in LaTeX -- in particular, computer modern sans serif?

Thanks

Sure, you can load them the same way you would in LaTeX. But that needs a full TeXDocument.

Ideally this would be automated from the fonts in the theme, but I don't have time to figure that out currently...

[RpfR2000]

I see. This is a great addition to Makie, thanks!

Sorry -- to be clear, if I loaded in the font via a TeXDocument, would it apply to all fonts in the plot (e.g., for ticks, axis labels, titles, etc.)?

[RpfR2000]

This attempt does not seem to do anything to the fonts. Clearly I need to pass the tex doc somewhere but I don't know where.

using Makie, MakieTeX
using CairoMakie
fig = Figure()
doc = raw"""
\renewcommand{\familydefault}{\sfdefault}
"""
tex = CachedTEX(MakieTeX.texdoc(doc))
ax1 = Axis(
    fig[1, 1], ytickformat = x -> latexstring.(string.(x)), xtickformat = x -> latexstring.(string.(x)) 
)
heatmap!(ax1, Makie.peaks())
fig

You aren't using tex anywhere though? The formatting functions would have to return a complete TeXDocument. Here's an example:

function num2tex(num)
    return TeXDocument("""
\documentclass{standalone}
\usepackage{amsmath}
\begin{document}
\renewcommand{\familydefault}{\sfdefault}
$$\int x = dx$$
\end{document}
""")
end
fig = Figure()
ax1 = Axis(
    fig[1, 1], ytickformat = x -> num2tex.(x), xtickformat = x -> num2tex.(x)
)
heatmap!(ax1, Makie.peaks())
fig

It's been a while since I wrote TeX so that document might be wrong. But this is what you would do.

[RpfR2000]

I see, thanks. This attempt gives an error that I am having difficulty parsing. The TeX document compiles just fine on its own.

using Makie, MakieTeX 
using CairoMakie
function num2tex(num)
    return TeXDocument(raw"""
\documentclass{standalone}
\usepackage{amsmath}
\renewcommand{\familydefault}{\sfdefault}
\begin{document}
Test
\end{document}
""")
end
fig = Figure()
ax1 = Axis(
    fig[1, 1], ytickformat = x -> num2tex.(x), xtickformat = x -> num2tex.(x)
)
heatmap!(ax1, Makie.peaks())
fig

Ooh yeah I missed that you are using it like that. That doesn't work in recent versions of Makie unfortunately, because of changes to the way text is laid out. I want to change that at some point but it's a bit tough.

If you need that specific font and have a file for it (.ttf, .otf, or whatever) then you could use Makie's native font capabilities to point to it (https://docs.makie.org/dev/explanations/fonts) and reserve MakieTeX for labels and other, larger text that you can create independent label blocks for.

[RpfR2000]

Okay, thanks. Using a .ttf file works fine for the most part. Perhaps it's worth keeping this issue open though?

[asinghvi17]

Yes, at some point I want to unify these two approaches.
