First at all, thank you to everyone that help me!.
I need to make a Pareto chart, but the values that I have are millions and I don't know to manage them. I made it but in "Expressions" because I do not know to group all the tests in one "Tests_ED" by example, or whatever. That case is, when I made it by Expressions It's not avalible to create a Pareto.
The tablesource is something like that:
#/ Serienummer/ Time/ Status /Article/ Line/ Öffnungdruck/ uevschliesdruck/...
Status: Values are "IO" or "NIO"
IMPORTANT: Status shows when IO or NIO is, but I need to calculate just when NIO is.
Öffnungdruck and all tests : Values are Numbers like "16,93"
Bar chart that I get working with expressions. It is good but 'till not represent what i need
