Persistent data of group items not showing in analyzer

[papaPhiL (Philipp Fink)]

Hi all,
I wonder what I am doing wrong. I am missing the analyze graph on group items.
Config:

I can see “something” as the graph is part of the background of the widget,

but if I click on it, nothing will appear:

I can see the analyze-graph on each Temperatur Item,

but not on the group item .

I use version: 3.1.0.M3, but the problem exists since I started OH3 a couple of month ago.
my setting is

and those are my persistence_files:

phil in openHAB in /etc/openhab/persistence🔒
❯ ls
mapdb.persist  rrd4j.persist

phil in openHAB in /etc/openhab/persistence🔒
❯ cat mapdb.persist
Strategies {
    // for rrd charts, we need a cron strategy
    everyMinute : "0 * * * * ?"
}

Items {
    * : strategy = everyChange, restoreOnStartup
}

phil in openHAB in /etc/openhab/persistence🔒
❯ cat rrd4j.persist
Strategies {
    // for rrd charts, we need a cron strategy
    everyMinute : "0 * * * * ?"
}

Items {
    // persist items on every change and every minute
    * : strategy = everyChange, everyMinute
}

Thank you for your time!

Do you persist the group or the individual items?
And what’s the value of the group?

I assume I persist everything? see the astrix in the persistence-file.
something is persistent, because I can see the graph in the widget, just not the analyzer.

@Marijn_Oudijk

And what’s the value of the group?

The value of the group is always the average of it’s members.

See

OH3 MainUI Group item not displayed in chart/analyze/graph (persistence)

Hi, Is anybody facing the same issue that the values of a group item aren’t displayed in the analyze chart? [image] However, the small graph shows a line: [image] This is how the group item is set up: [image] [image] State Description: [image] All values are stored correctly in a MariaDB 10 database: [image]

In summary, MainUI charting for Groups is not yet resolved.

I assume I persist everything? see the astrix in the persistence-file.

I’m never sure about that, for Groups, which get special handling in persistence i.e. it wants to persist members instead.
You can use API explorer to verify you have data for the Group Item.
