Use the MAX consolidation function (CF) in a PRINT or GPRINT, such as:
	PRINT:aa_out_MAX:MAX:%.1lf
or
	GRINT:aa_out_MAX:MAX:%12.1lf

Note that this is independent of the CF specified in the archive of the data
source in the RRD file.  That is, you can get the MAX of the graphed MAXes &
the MAX of the graphed AVERAGEs, as well as the LAST of both.  See the
attached rrdgraph snippet.
