ok, thanks. i thought there was a accurate solution, since i figured that
the amount of data points is so low that even lowering the resolution
wouldn’t help. but then i remembered that somebody told me that binning
would most likely be the only solution and now your mail.
i’ll certainly manage to do that, then; thanks again!
