Known "Bug 58562 - EDITING: copy and paste of CHART from Calc looses Y values" @Clemens Eisserer Thank you for your attention! *** This bug has been marked as a duplicate of bug 58562 ***
I am not sure this is a 1:1 duplicate of 58562, as I am able to reproduce the issue only with one of the two diagrams also with 3.5.7, while the other diagram works perfect in 3.5.7.
