I need to insert a Report chart into a VisualForce page on a Custom Object named "Visit Preparation". Simple enough...

Where I'm struggling... I need to filter the Report's chart using the ID of the Account associated (via lookup relationship) with Visit Preparation Records.

I've created a field that pulls the associated Account's ID named "Salesforce_ID__c".

How do I filter the inserted Report Chart's data by the ID shown in the Salesforce_ID__c field?

Thanks in advance!
