display data format problem

[cadbury]

hi all, here's my pb :

i've configured a host which is on my local network
and an item with simple check and icmppingsec for this host

as the host is on the same LAN, the values returned are under 0.00sec
but in the latest values, and on the graph of these values,
only 3 digits are diplayed (see the attachement)
all the numbers are diplayed as 0.00sec

as the graph seems to be correct, i presume that the corrects numbers are in the database, so it is just a matter of formating

can I change the format of diplayed numbers?
thx in advance

correction :
"as the host is on the same LAN, the values returned are under 0.00sec"

the values are between 0.01 and 0, and not negative
