STYLE > Setting playback to sawtooth or modeshape styles
For transient analyses a "sawtooth" (1 => n, 1=>n) display generally looks more intuitive since it gives the impression of "start to finish".
However you can opt for "modeshape" (1 => n =>1 => n ...) mode if you wish (this is the default for static and eigenvalue analysis types).
Examples of the two different modes (from their panel) are shown here in diagrammatic form.
