What you did not save you can not graph. Making graphs takes a good deal
of planning before you implement it.

But if you want to store graphs you might as well plan to take weekly
snapshots.

At present for some measurement environments I take daily snapshots of the
graphs. Combined with some scripting this results in almost up-to-date
monthly graphs. They make pretty pictures in quarterly reports.
