The query below gives me back a series of computed values.  
I would like to plot those values in Kibana.  
I think I should be able to do this in Visual Builder, but I'm stumped.  
There is a calculation aggregation, but it needs an aggregation as input.  
I don't have an aggregation, I have a series of documents.

GET /log-lines\*/\_search  
{  
"query": {  
"bool": {  
"must": [  
{"match": { "server": "[large.pod2.cache2.yyz.cdx-test.example.com](http://large.pod2.cache2.yyz.cdx-test.example.com)" } }  
]  
}  
},  
"size" : 0,  
"script\_fields": {  
"lag\_seconds" : {  
"script" : {  
"lang": "painless",  
"source" : "int lag = doc['ls-timestamp'].date.millisOfDay - doc['@timestamp'].date.millisOfDay; return ((lag \< 0) ? lag + 1000 : lag) / 1000;"  
}  
}  
}  
}

I don't believe this is currently possible, sorry!

I had thought the Visual Builder could do anything timelion could do, but clearly not.  
Doing the subtraction should be do-able in timelion I think -- though I haven't tried it yet.

I also changed the title to emphasize this is not a "Kibana scripted field" I'm asking about.  
I'm asking about computing a value for each record (that is computable from the data in each record).
