Today i'm searching how to convert a duration field from ms to sec into a line visualization.  
as i can't change the advanced params or create a scripted field, i'm trying with the "json input" field but i'm not sure it's today possible (kibana v7.8.1).  
Have you a solution please ?  
Thanks

The duration formatter which is part of the index pattern should allow you to do this: [Manage index pattern data fields | Kibana Guide [7.15] | Elastic](https://www.elastic.co/guide/en/kibana/current/managing-index-patterns.html#field-formatters-numeric)

thanks Joe,  
but i can't manage index pattern (reserved for admin ☹ )  
So i try to find another solution. Is it possible in the "json input" of my visualization ?
