[Sugar-devel] GSoC idea: Chart/graph-making activity

[Wade Brainerd]

This whole thing brings to mind something that I've been curious about for
awhile.

What's the "recommended" way to transfer data between activities?

Say, I record some data in Measure and want to import it into Chart.  Or I
generate some data in Finance and want to import it into Chart.

Is the Clipboard the way to do it?  IE, should we support specialize "copy
as text/csv" (or whatever) and "paste text/csv" in our activities?

Same goes for transferring of pictures.  If I take a picture in Record and
want to paint over it in Colors!, is Copy in Record and then Paste in
Colors! the way to go, or should I have Colors! open the Record Journal
entry?

Thanks,
Wade
