Hi team,  
We are trying to implement vs prior concept in kibana, where as we used serial Diff using TSVB, we got output with comparison of previous month, but if we use the calendar using date range selector, the value is 0, and also when we select both months (Dec and Jan ) it giving the prior comparison for DEC, whereas if we select only DEC it not giving the Output.

Please help us...

Thank you !
