That made the deal, i tried to change a bunch of parameters before but i am not yet familiar enough with the par("usr") one...
Thank you very much!

I think this part is what's not transferable to a smaller range of
y-values.
par("usr")[3] will be much smaller when ylim goes to only 2 instead of
70. Subtract 2 from that, and you have a very different kettle of
fish.
Without knowing anything about myobject1 and myobject2 I could be
completely ooff the mark, of cours.
