# set_visible()

Shows or hides this layer. The heatmap updates with it.

Hiding does not delete the weights. Set it back to `True` and the original weights show again.

### Signature
```python
layer.set_visible(visible) -> None
```

| visible | Meaning |
|---|---|
| `True` | Shown. |
| `False` | Hidden. |

### Example
```python
layer = api.layer("Arm")
layer.set_visible(False)
print(layer.visible)
```
