Your question is not clear, at least to me, nor is it apparent how  
this is related to nagios. PNP4nagios and mrtg are two different  
things, getting data from two different places. Both use their own RRD  
databases for backends.

RRD files are units-agnostic. They just store a number and it's up to  
the presentation layer to determine what units that number is (bits,  
Kb, Mb, apples falling/second, etc).

If you're having a problem with MRTG graphs, the proper forum would be  
the mrtg listserv.

If you're having a problem with pnp4nagios graphs, the proper forum  
would be pnp4nagios-users.
