present the user an overview of the current recording and move through the recording when a zoom is
in effect. In this screen, the user can use its fingers inside the main graphic window to manage the zoom
by pinching and move through the recording by dragging. Selecting a recording will cause the screen to

of minimum FFR. The user can scroll through the recorded measurements to see changes of Pa
and Pd over time. Pressing the FFR button in the data window will return the marker to the
point of minimum FFR.
