How to create intervals based on length in Jaspersoft server 7.1.

[enrico.gironella]

Hi there!

I'm a fresh user of jaspersoft server.

I have X occurences, each of them associated to a numeric attribute "length" and  I would like to create intervals based on such an attribute in ad hoc view (crosstab).

What I need is basically to create lenght bands to find how many occurrences happened between each range. Something like this:

LENGTH RANGE                             NR. OCCURRENCES

0<10                                                   40

11<50                                                 56

>51                                                     22

 

Thank you for your advice and support.
