How to underline a text in julia using Latex String?

[sivabkumar]

using Plots

using LaTeXStrings
x = [1,2,3,4,5]
y = x .^2
plot(x,y,label = L"\underline{x}")

This code will give an error

but instead of \underline if I am using \overline work.

That is

plot(x,y,label = L"\overline{x}")

But I need \underline.

Please solve my problem.

Thanks in advance

There is nothing that LaTeXStrings can do about this — it doesn't do any rendering, it just sends the \underline{x} to the plot backend. So your are limited by whatever math formatting is supported by the math display of your plot backend.

If you are using the PyPlot/Matplotlib backend, see this stackoverflow question and matplotlib/matplotlib#14235

If you are using Makie, then it uses https://github.com/Kolaru/MathTeXEngine.jl to render latex equations, see Kolaru/MathTeXEngine.jl#121
