How to reset munin graphs

I'd like to reset all graphs for a certain host in Munin. Anyone who knows how I can do this?

Munin data is stored in Round Robin Database files (.rrd). These are stored under /var/lib/munin.

Each host and hostgroup will have it's own subdirectory under /var/lib/munin

Delete the .rrd files under the hostname in question, and your data will be zeroed out. Graphs will be re-generated after a few minutes.
