PlotWin with scroll on real time

[Uwe]

As far as I understand you want to show a 10s interval starting from a value that depends on the time ( and some other stuff I didn't understand ) - similar to the cpuplot example.

Then all you need to do is to increment the scales by one each second ( using setAxisScale(t, t +10.0, ...).

Uwe,
thanks,
that sounds good and is simple ... why do I have not this idea?!?!

but it's possible to implement a scroll bar per default? it works with zoom.
I need a default x-scrollbar so I can scroll through the hole plot every time ....

Sure, put a QScrollBar somewhere and connect its signals to slots, where you shift the range of the x-axis ( using setAxisScaleDiv() ).

F.e look at the event_filter example, that uses a QwtWheel for scrolling. Another sources for inspiration could be the ScrollZoomer/ScrollBar classes of the realtime example - but don't use them as they are, when you don't need a zoomer.
