I want to set ower/upper limit of y-axis range myself.
but I can't find any menu or parameters to do so.
RRDgraph have theses options.
In opsview-web/lib/Opsview/Web/Controllere/RRDgraph.pm
123 #if (defined $full_size_mode){ push @$rrdoptions,
"--full-size-mode"; }
124 if ( defined $upper_limit ) { push @$rrdoptions, "--upper-limit",
$upper_limit }
125 if ( defined $lower_limit ) { push @$rrdoptions, "--lower-limit",
$lower_limit }
126 if ( defined $rigid ) { push @$rrdoptions, "--rigid" }
127 if ( defined $alt_autoscale ) { push @$rrdoptions, "--alt-autoscale"
}

[*-u*|*--upper-limit* *value*] [*-l*|*--lower-limit* *value*] [*-r*|*--rigid
*]
By default the graph will be autoscaling so that it will adjust the y-axis
to the range of the data. You can change this behavior by explicitly setting
the limits. The displayed y-axis will then range at least from *lower-limit*to
*upper-limit*. Autoscaling will still permit those boundaries to be
stretched unless the *rigid* option is set.
