gausssmooth and 2 color graph

[solid]

  Ooups, the peak-artifact of the 'gausssmooth' is always here. Now it comes from the offset g=9.8 m/s² of the data. Only here (with the same phyphox program) it is visible with zoom..

---

If one subtract the offset before applying 'gausssmoth' and then add it, the peak-artifact is not visible. But it is not a good solution, is not it?   Anyway I give the "correction" here.
