LaTeX's lower indices in the legend are not shown correctly #265

For example: example

using Plots; pgfplotsx()
plot(1:20, rand(20,2), ,label=[raw"$y_1$" raw"$y_2$"], xlabel=raw"$x$", ylabel=raw"$y_i$")

The lower index in the axes shows as normal, but the ones in the legend are shown some kind of raw code instead of lower indices.

Looks like a bug in the Plots.jl wrapper. It seems they do some escaping, the legend entry that gets created is

julia> p = plot(1:20, label="\$y_1\$")

julia> p.o.the_plot.elements[1].elements[1].contents[end]
PGFPlotsX.LegendEntry(PGFPlotsX.Options(OrderedCollections.OrderedDict{Any, Any}(), false), "\$y\\_1\$", false)

It seems you can use LaTeXStrings to fix it:

julia> using LaTeXStrings

julia> p = plot(1:20, label=L"$y_1$")

bild

If you want to follow up on this, please report it to the Plots.jl repo.

It doesn't seem to work for me. I'm considering to report it to Plots.jl. Anyway, thanks!
