Guidelines on nagiosgraph

hi there,

If tried installing nagiosgraph 1.13 onto Nagios 3.0.6. Yet it just will not work, i cant get anything to write data to the rrd catalogue, and its impossible to draw any graphs (figure its due to no data being written). I get the perfdata.log allright, and my apache settings seems to be okay too, all configuration changes have been walked over several times now, and im stuck.

Can anyone help me please?
