The highlighted part of the Trace Map represents the part of the trace file currently displayed on the opened Chart. This highlighted area - the view area - is updated automatically when you start viewing another time interval of the opened Chart. When the time interval of one of the Charts changes, the Trace Map and all opened Charts are updated automatically.
