Knowledge Base Article Views numbers not matching with REST API output

I am using below REST API Call to get numbers of article and article view. It’s given me results however if I validate the same with advance metrics “Knowledge Base Article Views“ dashboard, I am not getting same results for View.

Also if I validate the article view on forum site its matching with API output. However the numbers are differ on metrics Dashboards.

This difference is with View metrics only and other metrics like # of article, comment and Post view are 99% close.
