DataReviewer - Dashboard Results


This sample shows how to fetch and display dashboard summary from a Reviewer dataset. The summary is total counts of a value in the specific or custom (user-defined) fields in the Reviewer dataset's REVTABLEMAIN or REVBATCHRUNTABLE tables. The summary displays the number of occurrences of a unique value in a field in these tables. The DashboardTask class exposes methods to retrieve these statistics and the field names from which statistics are generated. This sample fetches dashboard summary using the getDashboardResults function. The live sample retrieves dashboard statistics from a hosted instance of Data Reviewer for Server.
