Is there a function similar to `hline!` but defined only over a finite x-range? I.e. something like:

```julia
hline!([3], [-1, 0])

```

Where a line would be plotted at `y=3` from `x=-1` to `x=0`.

I am aware this can be done simply by plotting a range at fixed `y`. I just wonder if such a function already exists since `hline!` exists.

I don’t think there is such function, but you could build your own from:  
`plot!([-1,0], [3,3])`
