# updateChartDescriptor(_:)

Update the existing `AXChartDescriptor` for your view, based on changes
in your view or in the `Environment`.

```
func updateChartDescriptor(_ descriptor: AXChartDescriptor)
```

## Discussion

This will be called as needed, when accessibility needs your
`AXChartDescriptor` for VoiceOver. It will only be called if the inputs
to your views, or a relevant part of the `Environment`, have changed.
