You just have to specify the absolute path of rrd files when
calling the functions, for instance,

use RRDs;

$rrdfile = '/path/to/rrd/file.rrd';
$imgfile = '/path/to/img/file.png';

RRDs::create($rrdfile, ...);
RRDs::update($rrdfile, ...);
RRDs::graph($imgfile, @options,
		"DEF:ds0=$rrdfile:dsname:AVERAGE", ...);
