Displacements measured for each frame, on the trace selected by the "Amplitude trace #", are displayed with respect to their frame numbers. The "Frame list" parameter selects the frames to be measured, and the order in which they are presented. The Frame number for each point on the X-axis corresponds to the frames' position in the sequence in which frames are presented. These numbers do not represent actual frame numbers unless frames are displayed in sequence, beginning with frame 1, and no frames are excluded.
The trace amplitude measurements are taken the same way they are for the "Raw trace amplitude vs step cycle" graph. Deleted frames, and frames whose tag values are not in the "Tag list" are excluded.
