Tetragonal fazda mod değişimi, modun sırasını değiştirir. Aynı olmayan modların yerdeğiştirmesi Tetragonal fazda simetriği bozar. Bu durumda modun özelliği, simetriklik ve kaynağın özelliği değişir.

Jürgen Weippert

If you want a visualization of modes, the best idea would probably be to directly ask people who already did DFT on it for their output data. This is the first example I found spontaneously:

Article Symmetry-Forbidden-Mode Detection in SrTiO 3 Nanoislands wit...

It already has displacement data for some modes, so they should have data on it.
