Hello,
I'm looking to implement a trends graph on the HMI screen with particular user capabilities. I'd like to be able let the user select the timescale on which to view the data (by minute, hour, day, week, etc). What are ways to implement this?
From what I can tell, the simplest way would be to have different data samplers for the same variable that logs data at different time increments. But obviously this would be memory intensive. Is there a more efficient solution?
Thanks!
