JohnnyBoy22 Posts: 19 Rating: (1)	Hello! I am trying to display historical data in a table format. I have a sensor that I want to display 3 values for from the past 3 hours (hour 1, hour 2, hour 3), as shown: Hour 1: 457 Hour 2: 457 Hour 3: 458 I have created a historical data item to log data from the sensor tag. As far as I have read, the only way to do this is by using a script to read data from my historical. Is there an easier way? If not, is there some example script out there I can look at to retrieve data and put it in a table format. I am using a TP2200 and WinCC Advanced v12. Thanks! John
