Hi Renaud,

Thanks a lot for helping !

Actually, I did think about such a function (jitter), but it didn't really solve the problem, as it may change nothing for some overlaying points and even create new cases of overlaying points. Moreover, it modifies every coordinates, even if it is not necessary.

I hoped there might be an heavier function able to change coordinates in an let's say intelligent or surgical manner...
