MRTG & Hobbit

I have been wrestling with this for a few days and haven't found anything pertaining to this in the archives - When I do the MRTG integration as described by Henrik, it seems to default to bits /second instead of bytes? Is there a way to change this? Also, is there anyway of showing the percentage and the units of measurement on the graph as on a standard copy of MRTG? Thanks
