You're already calling "rrdtool graph".  So the elements in there are
doing all the calculation for you.  It's just putting it on the graph
via a GPRINT.

Either add or change that to a PRINT line, and the data will go to
STDOUT rather than within the graph when you run the tool.

PRINT:cdefa:MAX:"Maximum\:%8.2lf %s\n"
