I’ve used the following code:

```python
v = GetActiveView()
[(Show(s).RescaleTransferFunctionToDataRange()) for s in GetSources().values() if servermanager.GetRepresentation(s, v) is not None and GetDisplayProperties(s, v).Visibility==1]
Render()

```

Second line filters uninitialized sources (see [this post](https://discourse.paraview.org/t/obtain-information-if-proxy-is-visible/2346/11)).  
`Render()` may be omitted if you don’t need to redraw view right away.
