# Latex typesetting in Plots with plotly backend?

I am using Plots.jl and plotly for making plots, but I would like to have my legend, title and labels typed in latex. Using LaTeXStrings and the syntax L"…" works for gr and pyplot backends, but not for plotly. Does anyone have any idea how to write latex strings with plotly?

thanks,
bruno

This doesn’t answer your question, but if you want fully customizable LaTeX, consider

Currently it doesn’t work in the Juno IDE, but it does work in IJulia, if you copy the correct fonts to the mathjax directory:

• copy the jax -folder to C:\Users\<username>\.julia\conda\3\Lib\site-packages\notebook\static\components\MathJax or wherever this is on your system. Note that there might be more MathJax folders, (e.g. C:\Users\<username>\.julia\conda\3\pkgs\notebook-6.0.3-py36_0\Lib\site-packages\notebook\static\components\MathJax, but only one is the true source for the server.

The background seems to be that Mathjax changed the default font to TeX, but the current distribution that comes with Jupyter only contains Stix-Web. I have posted this recently on stackoverflow.

using Plots, LaTeXStrings

plotly()
Plots.plot(1:4, [[1,4,9,16], [0.5, 2, 4.5, 8]],
labels = [L"\alpha_{1c} = 352 \pm 11 \text{ km s}^{-1}" L"\beta_{1c} = 25 \pm 11 \text{ km s}^{-1}"],
xlabel = L"\sqrt{(n_\text{c}(t|{T_\text{early}}))}",
ylabel = L"d, r \text{ (solar radius)}"
)

produces

EDIT:
The following lines make it available in Juno. Make sure, Conda is installed and the files are copied as described above.

using Plots, LaTeXStrings

plotly()

import Conda.ROOTENV

function mathjax()
mathjaxdir = joinpath(ROOTENV, "Lib\\site-packages\\notebook\\static\\components\\MathJax")
mathjaxfile =  joinpath(mathjaxdir, "MathJax.js?config=TeX-AMS-MML_HTMLorMML-full")
return """<script type="text/javascript" src="$mathjaxfile"></script>""" end function Plots.plotly_html_head(plt::Plots.Plot) local_file = ("file://" * Plots.plotly_local_file_path) plotly = Plots.use_local_dependencies[] ? Plots.local_file : Plots.plotly_remote_file_path if Plots.isijulia() && !Plots.ijulia_initialized[] # using requirejs seems to be key to load a js depency in IJulia! # https://requirejs.org/docs/start.html # https://github.com/JuliaLang/IJulia.jl/issues/345 display("text/html", """ <script type="text/javascript"> requirejs([$(repr(plotly))], function(p) {

});
</script>
""")
ijulia_initialized[] = true
end
return """$(mathjax()) <script src=$(repr(plotly))></script>"""
end
