Hello 

I do also not understand 100% correctly your question...

-> so do you want to set in Runtime a specific timerange?

This is not that easy in WinCC Advanced Runtime. You can only se the axis mode to time and use a Time interval in seconds. the only way to dynamise it is to use a Tag for the external Time. This is where the trend starts. SO you can only shift the start Time dynamically but not the time interval. You can also not set start and stop time of the trend in runtime. (in other WinCC systems its possible)

But you use the navigation buttons in runtime in the control to navigate to the used timespan
