I am logging a daily flow tag with Wonderware Historian. I need to give the user the ability to get the top 5 daily flows within a specified date range, as well as the date of each. Note that the tag is logged every few seconds, so each day has lots of log entries.
Basically, I first need to find the latest logged value for each day, then sort those in descending order.
Has anyone done anything like this? Any suggestions appreciated.
