Additional context

I posted about this problem here https://discourse.pi-hole.net/t/potential-bug-total-queries-over-last-24-hours-empty/69602 already. I just want to make sure to cross-reference this.

What API is responsible for updating the live data? I can check what the API returns for me then.

What API is responsible for updating the live data?

More than one:

• Total queries 24h graph: admin/api.php?overTimeData10mins;
• Clients over 24h graph: api.php?overTimeDataClients&getClientNames;
• Query Types graph (this is working in your screenshot): api.php?getQueryTypes;
• Upstream servers graph (also working): api.php?getForwardDestinations.

Okay, so I noticed that admin/api.php?overTimeData10mins (apparently only executed once when loading) returns

{"domains_over_time":[],"ads_over_time":[]}

Not sure if that is correct.

api.php?overTimeDataClients&getClientNames returns

{"clients":[{"name":"fritz.box","ip":"192.168.178.1"},{"name":"localhost","ip":"127.0.0.1"},{"name":"raspberrypi.fritz.box","ip":"192.168.178.23"},{"name":"localhost","ip":"::1"},{"name":"raspberrypi.fritz.box","ip":"<my public v6 IP>"}],"over_time":[]}

This issue was resolved after I restarted my Raspberry Pi.
