When framing, the horizontal axis denotes the frame number. This is to aid you in
the framing process as you can see how HFR changes between frames.
Relative Profile
The relative profile is a graph that displays the relative HFR values plotted against
each other. Lower HFR values correspond to narrower shapes and vice-versa. The
solid red curve is the profile of the current HFR value, while the dotted green
curve is for the previous HFR value. Finally, the magenta curve denotes the first
measured HFR and is displayed when the autofocus process concludes. This
enables you to judge how well the autofocus process improved the relative focus
quality.
