xnmgraph: how to use the instanceRE flag?

["Rauwers, Laurens" <rauwers@hitt.nl>]

Hello,
Using NV5.1.2 on DECUnix.

I'am trying to graph a CPU performance figure from a table. I want to graph
only instance 0, reading the man page of xnmgraph gives me a solution that
doesn't seem to work. Trying other possibilities: not working either.
The problem is that the grapher graphs all instances of the table, instead
of instance 0 only.

I'am using the following mib flags:
    -mib \".1.3.6.1.2.1.25.5.1.1.1:0::::::.01:\"

Is there someone out there who can give me a hint?
Thanks in advance.
