Sage 300 Web Screen - How to data populated in Activity Trend on the Dashboard?

Hello, 

Anyone can tell me how was the data in Activity Trend in web screen's Dashboard was populated? 

Am checking for the Shipment Value on the bar chart. Compared it with the Shipments information on the same date from Sage 300, but could not get the value tally. 

Appreciate if anyone could advise on this matter. 

Thank you.
