Because there is no raw data to begin with.  This is by design.
You are not storing raw data, you are storing rates.  You need
to understand what is happening when consolidation occurs to
appreciate the difference between AVERAGE and MAX for instance.

You have the option of using mySql or something similar.  This
is the type of database you should use if you want to get out
what you put in.  You also need to do maintenance on such a
database and you need to calculate each rate at graphing time.
