Using `pyplot` as backend, the following draws a rectangle:

```julia
pyplot()
plot([(1,1),(5,1),(5,3),(1,3),(1,1)])

```

while if I change `pyplot()` to `gr()`, a partial rectangle is drawn, and then an error message is generated: `GKS: Rectangle definition is invalid in routine SET_VIEWPORT`

**Question** : Why?

I do not get any error using `gr()` with that. But just to add, if you want to control the fill of the rectangle, etc, you can use:

```julia
julia> using Plots
julia> plot([(1,1),(5,1),(5,3),(1,3),(1,1)],
            seriestype=:shape,fillcolor=:green,linecolor=:blue,linewidth=3)

```
