No, you need another system for using that data. Usually it is passed to
one of the many RRD-based graphing system available. Some of them are
based on Nagios (NagiosGrapher, PNP) or you can usually integrate it
with other tools like Cacti with some additional work. My method was to
use a daemon reading the performance data pipe and caching data for a
sort period, and a cacti script to read it back. see:

Search around, you will likely find other applications and utilities for
doing that.
