This is something that is wrong in the front end you're using. In it
you find something similar to "GPRINT:ds1:AVERAGE:%6.2lf" and

This piece of code prints, as you might guess, the average and maximum.
Perhaps you could add a line that also prints the minimum.

Note that this is not really an MRTG question, you should subscribe to,
and post on, the rrd-users list.
