hey all,
apologies but currently I am new to Elastic and Kibana and need some guidance. I have a custom app that puts an index that contains a 'payload' field which is a String and stored as-is. That 'payload' field is overloaded and can contain different types e.g. Integer, Floats, String depending on another field called 'path'. If the 'path' is equal to some fixed value A the 'payload' field should be interpreted as a string otherwise if the 'path' field is equal to B the 'payload' field should be interpreted as an integer.
I was wondering if I want to create a time series graph in Kibana that displays this 'payload' field when the 'path' field is equal to B. Since it's a string I can't select it in Kibana so I need to convert it to an Integer "on-the-fly". Wondering if this is possible? Assuming I can not change the source app but do the processing of the field in Elastic/Kibana part.
Will appreciate some ideas and guidance.
Thanks!

Hello,
Scripted fields might help you here?
> **[Scripted fields | Kibana Guide \[7.11\] | Elastic](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html)**
Please note they are expensive in terms of operations cost. If you can make mapping work at the site your data ingestion - it might get easier.
Thanks
Bhavya
