Sakthivel Velumani 0004626ac7 Fix bug in QT scope 
The UE copies scope data not in a single buffer to avoid overwiring in case of multiple slots processing in parallel. But the scope upates data from single buffer thats assigned during selection. A getPlotValue() method is created to update the data pointer on every timerEvent.
