Are you asking how to script a temporary data holder for the past 8 hours without using historization? I think you could insert data to the historian, and remove it. I don't think you will want to. * * * If you historize it: Ad Hoc trends from Ignition exchange is what I am using at the moment in some cases. PTurmel has a really nice viewer project as well. There is a realtime mode on the power table. I think you want the ad hoc trend though. I also use a timeserieschart with historical setup like: now(0) and aritehmetic (now(0), -8,'hour) Maybe I don't know what a realtime tag is though. A tag has to be historized, or have it's past recorded into something via transaction or script to pull up that data. * * * > [@Perspective Power Chart - Transaction Group Data](https://forum.inductiveautomation.com/t/perspective-power-chart-transaction-group-data/51365/2): > > As far as I know there is no filtering option available for the power chart component. About the best you can get is to dynamically change the start path. --- _[View the full topic](https://forum.inductiveautomation.com/t/power-chart-for-realtime-tags/65933)._
