Obsidian Charts + Dataview Financial overview

What I’m trying to do

I am working on my Finance overview.
I successfully created a table with all the values i need and the sum of them all

Table Portfolio, Crypto, Sparbuch, Konto, sum(Portfolio+ Crypto+ Sparbuch+ Konto) as Gesamt
From "Lab/Finanzen/Vermögen"
sort Datum asc

now i want to draw a historical graph for the value “Gesamt”. How do i do that?
