JSON input on result

Elastic Stack Kibana

Is it possible to do arithmetic operations on results? I'd like to subtract 1000 from sum. But it seems like JSON input treats _value as input value before doing the sum

Can you provide more context? What are you trying to accomplish? What Kibana plugin are you trying to apply sum to the response?

Thanks,
Nathan

I tried different Kibana visualisations. I started with Bar graph and SUM.
Normally sum of 5 elements (each element has a value set to 2), results in 10.
But when I add to JSON input: {"script":"_value+1"} it adds +1 to every 2, and all 5 values of '2' become '3', and the result is 15.

What I need is to add 1 to the results, so I am expecting 11. How can I achieve this?
