# Chart.DisplaySettingsChanged

Member of [Chart](https://help.ctrader.com/ctrader-algo/references/Chart/Chart/index.md).

## DisplaySettingsChanged

Occurs when one or several charts display settings change.

Environments: Desktop supported · CLI works differently · Cloud not supported.

- CLI: Only the cBot's own changes can raise it; no user can change a chart in the CLI.
- Cloud: Never raised: the cloud host does not report display setting changes.

event Action<ChartDisplaySettingsEventArgs> DisplaySettingsChanged;

api.Chart.DisplaySettingsChanged += handler  # handler(obj: ChartDisplaySettingsEventArgs)
