Kibana TSVB Metric -> Delta between today and yesterday

[Lucas_Erlacher]

Hello Community,

I have the following metric showing today's & yesterday's avg. session duration. Is there a way to show the delta between the 2 metrics? Thanks a lot for your help.

@Lucas_Erlacher, although TSVB allows math functions like that

it doesn't yet support math functions between two different series Support Bucket Script Aggregation · Issue #4707 · elastic/kibana · GitHub

It is very possible to be able to do it with vega though
