Jean, thanks for your answer. However, I fear gnumeric does something else. I have a data set with one very strong outlier, much farther out than 3* the IQ and according to this definition it should not be drawn. But it does, so it definitely includes the maximum value.
I am quite happy gnumeric does not clip the values at 3*IQ, but I still would like to know what it does exactly ... Hannes p.s. here are my data: HCI TT 2010 1 4 4 6 7 8 8 8 11 11 12 13 14 14 26 28 46 598 -----Ursprüngliche Nachricht----- Von: Jean Brefort [mailto:jean.bref...@normalesup.org] Gesendet: Montag, 24.
