Auto-Binner equal frequency

Hi,
I am wondering why in the Auto-Binner node with the choice of equal frequency as the binning method there are no bins with equal counts at the output.
Please take a look at the attached workflow. Each partition should have 30 lines.
Best,
Alfredo

Hi @alfroc,

this can happen, if in the column based on which the binning is created a value occurs more than once. E.g. if the value 5.1 occurs multiple times all rows belong either to bin (5.1, 6] or to bin (4.6,5.1]. In this case the bin (4.6,5.1] can have too many rows and another bin therefore gets to less rows assigned.

Cheers
