Fine. Than use (create) a CDEF "Make Data per minute" that multiplies the 
CURRENT_DATA_SOURCE by 60

In this case you would have to deal with consolidation on your own, graphing 
would be left to you and stuff. Please understand, that cacti relies on rrdtool. 
It uses most of rrdtool features but inherts all of its limitations
