Hello,
I have need to create a plot that shows how long the documents exists in the index
My first idea would be creating a scripted field that computes something like `now()-timestamp`
How can this be performed in kibana?

Yes, your intuition is good.
This is how to calculate the difference between 2 dates in Kibana scripted fields: [Kibana, getting todays date](https://discuss.elastic.co/t/kibana-getting-todays-date/85766/7)
There will be small differences in seconds based on how many documents the calculation is done for, but I guess you don't need that kind of precision.
