In `PyPlot.jl`, for example

```julia
using PyPlot, LaTeXStrings

rcParams = PyPlot.PyDict(PyPlot.matplotlib."rcParams")
rcParams["text.latex.preamble"] = "\\usepackage{siunitx}"

```

help me to directly use a Latex command from `siunitx` package like `L"\si{\nm}"`.

Is there any possible way to do the same thing in `Plots.jl` with a `gr()` backend?
