This should make it clearer:
($result,$xsize,$ysize) = RRDs::graph ( $file, @args );
print "The generated graph image in $file is $xsize pixels by $ysize pixels.\n";
foreach my $line ( @$result ) {
print "print output> $line\n";
}
The first returned value is a pointer to an array of strings, containing the
PRINT outputs from the RRDs::graph call.
