Different Panels on the Same Panel

is it possible to show data from another dashboard within a dashboard? Or use an Iframe in Html?

Reason: A panel gets information from the last 30 days and another from 30 minutes, but I can’t put it to get the individual information in last data in a single panel, only in 2 separate panels.

As far as I know nested dashboards are not possible. But you can replace
$timeFilter with time >= now() - 30d in the querry. If you use graphs, the time in $timeFilter will be used for scale. But other visualisations such as table or singlestat etc will work fine.
