Why not something like this? You might want to dynamically define a line for
the total, though.
my @args = ( $NameOfGraph,
"--title", "APstats",
"--start", "now-48h",
"--width=300",
"--height=75",
"--vertical-label=Active Users", '--lazy' );
my $i = 0;
foreach ( @rrdfiles ) {
push @args, (
"DEF:a$i=$_:auth:MAX",
"DEF:g$i=$_:guest:MAX",
"VDEF:amax$i=a$i,LAST",
"VDEF:aavg$i=a$i,AVERAGE",
"VDEF:gmax$i=g$i,LAST",
"VDEF:gavg$i=g$i,AVERAGE",
"AREA:a$i#00C000:auth$i",
"GPRINT:amax$i:\%6.2lf \%Susers",
"AREA:g$i#00C0FF:guest$i:STACK",
"GPRINT:gmax$i:\%6.2lf \%Susers");
$i += 1;
}
RRDs::graph( @args );
