Lofty idea: reproduce a dashboard outside of Sugar

We would like to "copy" some Sugar Dashboards leveraging the APIs that can be used to retrieve the metadata from the Dashboard.

We don't need full Dashboard functionality with filters etc, we just need to give a handful of non-Sugar users the ability to look at a specific Dashboard as a snapshot in time, on occasion.

We can use an api call to /Dashboards/<dashboardID> to get the dashboard metadata, including the ReportIDs for each of the dashlets included, but we can't use the /Reports API for stacked histogram reports (they are not simple Rows and Columns).

I attempted to use the reportIDs to get the metadata for each dashlet from the /Reports/<reportID>/chart API but I am having a lot of trouble interpreting and mapping the resulting metadata.

Is there an easier way that I'm missing or some "Rosetta Stone" for interpreting the metadata that I can refer to?

Thanks,

Francesca
