Dasboard plugin creation?

[tbaror]

Hello,

i would like to write customized Dashboard so i can choose kind of add widget as i would need and present then in my customized dashboard for that i would like to use Open Flash Chart 2 http://teethgrinder.co.uk/open-flash-chart-2/.

looking at Open Flash Chart 2 implementation is mostly using either JSON or Database query.

My question is is there a way to store RRD files in DB or retrieve data required directly into OFC2 ?

Please advice
