Hello,

how much data can be displayed also depends on the amount of data stored in the database.
Maybe the settings for the database in your project are not correct and therefore you see only values for at least 2 hours.

Please check the settings for the database at the WinCC OA system management.
As we do not know which database you are using we cannot tell you which settings need to be checked and probably modified.

If you need further information please send a detailled support request to the official support.
How to make a service request is described at the FAQs.

Is there any data in your database that is older than two hours?? are you keeping enough archive files online?
