Thanks mpb, the problem is that I am not always allowed to create new columns to configure the level names since I use Graph Builder to explore data in different and large tables with many variables and work according to what I find, manually create new columns to wrap the numeric variables in correct range values is too time consuming, I will use it for specific reports. I will continue looking for a way to perform the ranges in a more friendly way and post it here so more people could benefict from it.
Best solution that I have found until now, appart from your advice, is to change data type from numeric to character in the variable to wrap, this way the wrap method displays one level by category and it doesn't repeat values, now we just need to know how to group them in customized ranges.
Thanks again.

Asier
