Probably a silly/simple question… I have tried to strip down the essence of my problem to illustrate what I want to do — the example doesn’t fully illustrate the usefulness:

The idea is to define a label for a plot using LaTeXStrings notation, say:

```
plot!(label=L"x")
```

and replace the `x`

with something else, say `L"\frac{\Theta}{T}"`

.

So my attempt was:

```
xx = L"\frac{\Theta}{T}"
plot(f,label=L"$(xx)$")
```

This doesn’t work.

I hope this gives an idea of what I want to do — the `x`

I have used in the example will in reality be some `f(x)`

… if I insert the true expression for `x`

(say, `L"\frac{\Theta}{T}"`

), the label expression becomes long/cumbersome to type, and I’m hoping I can replace the `x`

by interpolation/substitution – somewhat like macros in LaTeX.

Any ideas of how to solve this?
