This component is a visual representation of the memory length. It shows which part of the memory length is currently visible on the diagram. It also shows the position of the trigger.

The entire width of the overview visually represents the memory length. The large rectangle represents the currently visible part of the memory length. It can be dragged to the left or right to show other parts of the buffered signals on the diagram. If the cursor is above the rectangle, its size can be increased or decreased by scrolling the mouse wheel. The trigger can also be dragged onto a new base position.
