I'm embedding a grafana chart into my dashboard, an have used this library flow as a starting point.
I've made a number of changes to the flow (and yet more to come), and it seems to work OK, except the iframe seems to disappear;
- When I leave my phone for even 3-4 minutes
- When I refresh (F5) my browser (Chrome)
- Occasionally when I change browser tabs for a few minutes.
Neither selecting different time button or refreshing the display returns the iframe, and the only way I've found to get it back is to select a different dashboard menu item, and then reselect this menu item again.
I have attached my flow, together with a data source;
