Hi !

I have an xls file with 2 columns. One contains a code and the other contains numerics values.

I would like to create an attribute that group my data when there are a break on the values and group by code. For example :

code value

a 1 => group 1

a 2 => group 1

a 3 => group 1

a 10 => group 2

a 11 => group 2

b 1 => group 3

b 2 => group 3

I saw "AttributeRangeMapper" but I have to indicate the bounds. In my case I would like that the bounds are create automatically because my datas change every time.

My values can be integer or decimal.

Thanks !
