I found the following code in this discourse (there seems to be a couple of versions of it):

```julia
import Plots as plt
ang = range(0, 2π, length = 60)
ellipse(x, y, w, h) = plt.Shape(w*sin.(ang).+x, h*cos.(ang).+y) # Returns a Shape object
myshapes = [ellipse(x,rand(),rand(),rand()) for x = 1:4]
plt.plot(myshapes)

```

and I think this worked a few weeks ago. But now it does not work…

The result is the same as the following code (which still works):

```julia
ang = range(0, 2π, length = 60)
ellipse(x, y, w, h) = w*sin.(ang).+x, h*cos.(ang).+y # Returns a tuple
myshapes = [ellipse(x,rand(),rand(),rand()) for x = 1:4]
plt.plot(myshapes,st=:shape)

```

and produces:

_Question_: Has there been a breaking change in `Plots` so that `Shape` doesn’t work any more? [Or do I do something wrong?]

There were a few changes regarding shapes lately,  
such as  
[https://github.com/JuliaPlots/Plots.jl/pull/3436](https://github.com/JuliaPlots/Plots.jl/pull/3436)

does it work on 1.13.2?

I don’t understand what’s going on… Let `myshapes` be defined as [just so we know which `myshapes` version I’m talking about]:

```julia
ang = range(0, 2π, length = 60)
ellipse(x, y, w, h) = plt.Shape(w*sin.(ang).+x, h*cos.(ang).+y) # Returns a Shape object
myshapes = [ellipse(x,rand(),rand(),rand()) for x = 1:4]

```

1. I use `Plots v1.15.1`.
2. If I do `plt.plot(myshapes)`, I get an error message. Note: `myshapes` is a vector of `Shape`s.
3. If I instead do the following, then things _work_:

```julia
plt.plot()
for s in myshapes
    plt.plot!(s)
end
plt.plot!()

```

To me, this appears to be a bug in how the recipe “unpacks” the vector of `Shape`s???

Or is the recipe _changed_ so that it cannot plot _vectors_ of shapes?

I can confirm that this works on Plots 1.0.0, but not on 1.13.2. Can you open an issue on github? This is a good test example

This should be fixed on 1.15.2

Seems to work!

Thanks a lot!!
