Showing the tooltip on all panels at the same time has been a long standing request in Grafana and we are really happy to finally be able to release it.
You can enable/disable the shared tooltip from the dashboard settings menu or cycle between default, shared tooltip and shared crosshair by pressing `CTRL + O` or `CMD + O`.

### Help text for panel
{{<imgboxmax-width="60%"img="/img/docs/v41/helptext_for_panel_settings.png"caption="Hovering help text">}}
You can set a help text in the general tab on any panel. The help text is using Markdown to enable better formating and linking to other sites that can provide more information.

Panels with a help text available have a little indicator in the top left corner. You can show the help text by hovering the icon.
