Hi,

what is the syntax to plot *unfilled*/*empty* polygons (via `Makie.poly!`

) ?

Thank you for the tip.

AFAIU `wireframe`

is a 3D thing and does not correspond to what I am looking for.

I managed to plot what I wanted using `lines`

on closed sets of points separated with `NaN`

s.

I.e. moving from something like this :

```
for r ∈ rectangles
xm,ym,xM,yM=r.xmin,r.ymin,r.xmax,r.ymax
push!(polygons,Polygon([Point2f(p) for p ∈ ((xm,ym),(xM,ym),(xM,yM),(xm,yM))]))
end
poly!(ax,polygons,color = pcolors,strokewidth = 0.5)
```

to something like this :

```
xs = Vector{Float64}()
ys = Vector{Float64}()
for r ∈ rectangles
xm,ym,xM,yM=r.xmin,r.ymin,r.xmax,r.ymax
append!(xs,[xm,xM,xM,xm,xm,NaN])
append!(ys,[ym,ym,yM,yM,ym,NaN])
end
lines!(ax,xs,ys,linewidth = 0.1,color=:white)
end
```

I wish a keyword like `fill=true/false`

exists for `poly`

but could not find it…

Could also just set `color = :transparent`

on the polys

Ach… Thank you ! I was not able to find this through the docs.
