I just do a 
 graphdefang.pl --trim
once a month (just use an interval that suits your needs).

From graphdefang.pl:

--trim:
Trim the SummaryDB to cut out old data.  It trims out:
1.  hourly data older than 1.25x$NUM_HOURS_SUMMARY hours
2.  daily data older than 1.25x$NUM_DAYS_SUMMARY days
3.  all but top 25 sender, recipient, value1, value2, subject values
    for all dates prior to the current hour, day, and month..
