Automatically recognize if all data behave the same at night / on weekends / on public holidays--> determine time period for gap in my graph

[nickmuno510]

Hello,

When I plot a timechart, there are some empty buckets, which causes a gap in my graph.
In these gaps (values with 0 events) you can see from the time chart that there are significantly fewer or no events at night, at the weekend, on a holiday.
Is it possible to recognize automatically, from which time period (e.g. "every day from 04 to 06 tomorrow earlier" or "on weekends from 20 o'clock to 07 o'clock earlier) no data (0 events) are sent? Does this trend apply to all data values or only to certain data values?

Time diagram I have determined the following measures:
index="xyz" sourcetype="st_http" | bucket span=10m _time | chart count over _time by ID | foreach * [eval <> = if(isnull('<>'), 0, '<>')] | appendcols [ | lookup N_lookup phone as ID output m n | search town="Frankfurt"]
