Hi Nils,
I found that for the title and gr() backend one has to use the latexstring()
function directly instead of L"some latex code"
.
Below an example code
using Plots, LaTeXStrings
gr()
date = "07-08-2018"
titlestring = latexstring("\\mathrm{My\\, \\alpha\\, including\\, a\\, variable\\, date:\\,}", date)
plot(sin, (0:0.01:5*pi), dpi=300,
title = titlestring,
xlabel = L"\mathrm{My\, x-label\, (mJ/cm^{3})}",
ylabel = L"\mathrm{\alpha (m/s)}")
