This is determined by the actual DS definition the RRD tool library uses, which for the NCV collector is set by the NCV_<testname> environment variable, which is typically set in hobbitserver.cfg. Show us what you have for NCV_mysql in hobbitserver.cfg, and please read the sections on DERIVE and COUNTER in the rrdcreate man page.
