Scenario:  
-- 2 different indexes  
-- current\_Id in IndexA and doc\_Id in IndexB  
I have a use case where i have to display data, when a condition **current\_id equals doc\_Id**  
It should retrieve all records for which this condition is true.

I am using a Vega Sankey Visialisation.  
Attempted approach:  
I have 2 data sets specified,

**IndexA**

**IndexB**

Index A gives an array of stk3 bucket

I want stk3 values to be matched against the current\_id of IndexB, so that it filters out those records that matches that condition and further aggregation is performed on those selected records.

Error I am currently facing,  
'\* Infinite extent for field "y1": [Infinity, -Infinity]'

How do I go about this use case?

How do I access the stk3 variable in the second index ??

Hi @bandodkarD. Can you post the Vega code that you currently have? It might help us understand better.
