Consider for example,  
My json inputs

**Input**

{

"id" : 38769,

"workers\_list" : [1,2,4,3,1,1,2,3,4,3],

}

{

"id" : 38770,

"workers\_list" : [1,3],

}

{

"id" : 38771,

"workers\_list" : [1,2,4,2,1],

}  
My kibana report either a data table or a bar diagram  
**Output**  
|id|frequency|  
|1|6|  
|2|4|  
|3|4|  
|4|3|

In the sample output for the id - 1 ,frequency is set to 6 (in the first input three 1's and in the second one 1's and in the last input two 1's).

What i would do here is to convert that array to a `text` field which will make that field be analyzed on ingest. This way you can do a count aggregation and till will count all the elements of the array across the documents.
