Thanks @Bhathiya, I was able to figure out. I was having two different database for wso2am_stats_db defined and configured with data-sources for API manager and API Manager analytics, where as both should be configured to same db. Once i changed the data-source (WSO2AM_STATS_DB) of API manager to same database which is configured with analytics. It worked and i was able see all analytics on store and publisher.
got some help from following references: How to manage billing with WSO 2 AM (2.0.0)
