Motion-Width = ∑ Segment-Widths

You can edit the Segment-Width of each Segment with the Segment-Editor

When the X-axis unit is set to degrees, then, usually, the Motion-Width = 360

If the X-axis units are:

Radians, then usually Motion-Width =2×π.

Seconds, then Motion-Width = 60 / (Cycles / Minute)

Milliseconds, then Motion-Width = 60 000 / (Cycles / Minute)

To edit the X-axis Units:

Active Motion-Settings > Motion tab > Motion Units > X-axis
