</div>

Is there a way to get something like:

```auto
import holoviews as hv
plot = hv.Curve([0, 1, 2]) * hv.Scatter([0, 1, 2])
plot.elements

```

# expected output

[‘Overlay’, ‘Curve’, ‘Scatter’]

without having to parse the str(plot)

```auto
str(plot)
':Overlay\n .Curve.I :Curve [x] (y)\n .Scatter.I :Scatter [x] (y)'

```

</div>

Or at least get the base element?

Nevermind, also figured out:  
`np.unique([p.group for p in plot.traverse()])`
