Thanks a lot, I have checked time series , does not work for my purpose, I will check on the functional data explorer to see if it works.
The context of data is production time series from the back end of PI system, so the time stamps are not as regular control system and frequency base. I need to have tag profile over time for a series of tags (process parameters), the difference make me need to have both time and value for each parameter to have the graphs. I can make it one at the time but then the interaction between parameters can not be seen over time.
