Hi Alex, thanks for yuor answer.....I think probably my problem is 
related to the type of DS i used: maybe GAUGE is not appropriate for the 
values i'm collecting from the Ldap server; i think COUNTER fits better: 
i'll try to change.
First of all i'll take a look at your DOCs.....
By the way i have another begginner question: reading some examples on 
graphing i cannot understand some parameters used in the GPRINT statement:
As an example i point my attention to a GPRINT statement used to graph 
the total amount of bits passed trow an ethernet link

    *GPRINT:totBits:AVERAGE:" Avg  \\: %8.2lf %s\\n"

what does it mean the *%8.2lf* parameter ???

I looked at the man page of rrdgraph and i see that in the _format_ 
string there could be a *lf*, a *lg* or a *le* marker in the place 
"where the number should be printed"....
It's not so clear for me the meaning of these markers and, in the above 
example, the meaning of the *%8.2lf*.

Any help is welcome, thanks in advance,
