OH4 Chart Page shows wrong data

[Tuny (Sebastian)]

@Chriss89

If I visualize the same item in a chart page as an aggregat series with the aggregation function “Last”, I receive 28.503 as last value.
I receive the same value if I change the aggregate function to “Maximum”.

Can you please share the code of your aggregate page?
Can you explain a little what you expect the page should look like in your opinion?

Maybe this is a thopic that might be interesting for you:

Displaying delta-values in charts?

I do have classical items, which just add consumption of energy, water, … Is there a way to display delta-values from one item? What I’d like to achieve is: daily consumption perhaps weekly and monthly consumption based on just on value-increasing item. Or do I need a virtual proxy item, which gets filled daily/weekly/monthly…?
