#101 HTML Summary Maximum Only 24 hours

[Peter Payne]

The ability to determine the max/min from a graph is
provided in limited circumstances (e.g. not for
mtargets). However, there is no time specification on
the call to "RRDTool graph" and therefore the maximum
or minimum is only calculated on the default of the
last 24 hours. Perhaps a range specifier could be
provided to the doHTMLSummary function. Alternatively,
perhaps each call to a graph could generate a summary
underneath the graph that appropriately summarises that
particular graph. In particular it should be very easy
to calculate a MAXIMUM across a graph in which the
$MTargetsOps eq "sum()".
