The short answer is no.

The explanation is this:
MRTG takes the data and constantly consolidates it.  That means after 
a certain period (default is about 34 hours), the daily 5 minute samples 
get consolidated to a weekly format, then as time goes by, they get 
consolidated into a monthly format, then into a yearly format.  You 
loose the granularity.  There is no graceful way to save the data.  Maybec
 opying the graphs daily, realizing that you won't have access to 
the actual data.  Or exporting the data daily into a mysql database or 
some other "growing" database.  

The smart aleck answer is you already have it.
Look on your weekly graph.  The graph is right there, just a little 
less detail than when it was shown in the daily graph.

Switch over to RRDTool, define how many of each sample, the create your 
own collection script.

Is there a way to get the graphs from a different day .?

    Lets say I want a graph from last week Wednesday from 2 am to 6 am.
Is there a script or something, somewhere, that allows me to do that?

            Thanks,   Gabriel.
