I would like to create a NSQL data provider which can be used in multiple graph portlets.
These portlets need to show actual usage data for different attributes of the projects.
E.g. A project has (odf-) attributes for Goal and Customer. I want to create pie-charts for actual usage as a percent of total, one chart displaying a break-down in Goals, another for the Customer field. Can I create an NSQL which can serve as a data provider for both of these portlets?
