I'm sorry, but I don't quite understand what you're asking for.

It is possible to use an arbitrary date for start and end of graphing.
If you have an archive with data in that range, you should see data.

Changing existing data in the RRD is more difficult.  You can dump the
data out of an RRD, modify the data, then use it to input into another
RRD.  That might be easiest if you need to do some changes.
