How to subtract field value from constant and display in Timelion?

Elastic Stack Kibana

Hi,

I am using ELK GA 5.0.0. I have a timelion visualization like below;

.es(index=myindex-*,q='fielda:data1',metric=max:my_info_a).label("Max")

This plots max value of my field my_info_a. But what I want is, I want to subtract this number from 100, and then display max of that value. Is this possible?

Thank you.

Using .subtract(100).abs() is mostly equivalent. It falls apart if you're dealing with values over 100 though.

Timeline works by chaining operations together, so subtracting by a number is pretty simple, but I don't know the expression language well enough to subtract the value from a number.
