[Xymon] integration of foreign graphs

Hi !

Is there any "easy" method to integrate foreign graphs into xymon or rather into of an existing page of a host ?

The background is, i've got an script from my colleagues, which gathers data from ibm-Scale-Out-network-storage (SONAS), generats rrd's and corresponding png's which i want integrated in one page of xymon .....

Any hint is welcome ...

thanks & cheers
