* instead of simply plotting a single metric. If $graph is not set, then we are (hopefully),
* plotting a single metric, and will use the commands in the metric.php file.
*
* With modular graphs, we look for a "${graph}.php" file, and if it exists, we
* source it, and call a pre-defined function name. The current scheme for the function
* names is: 'graph_' + <name_of_report>. So a 'cpu_report' would call graph_cpu_report(),
* which would be found in the cpu_report.php file.
*
* These functions take the $rrdtool_graph array as an argument. This variable is
* PASSED BY REFERENCE, and will be modified by the various functions. Each key/value
* pair represents an option/argument, as passed to the rrdtool program. Thus,
* $rrdtool_graph['title'] will refer to the --title option for rrdtool, and pass the array
* value accordingly.
*
* There are two exceptions to: the 'extras' and 'series' keys in $rrdtool_graph. These are
* assigned to $extras and $series respectively, and are treated specially. $series will contain
* the various DEF, CDEF, RULE, LINE, AREA, etc statements that actually plot the charts. The
* rrdtool program requires that this come *last* in the argument string; we make sure that it
* is put in it's proper place. The $extras variable is used for other arguemnts that may not
* fit nicely for other reasons. Complicated requests for --color, or adding --ridgid, for example.
* It is simply a way for the graph writer to add an arbitrary options when calling rrdtool, and to
* forcibly override other settings, since rrdtool will use the last version of an option passed.
* (For example, if you call 'rrdtool' with two --title statements, the second one will be used.)
*
* See ${conf['graphdir']}/sample.php for more documentation, and details on the
* common variables passed and used.
