+
+ This example generates a graph of the data series in blue (LINE2 with
+ the scaledobs virtual data source), confidence bounds in red
+ (scaledupper and scaledlower virtual data sources), and potential
+ failures (i.e. potential aberrant aberrant behavior) marked by vertical
+ yellow lines (the fail data source).
+
+ The raw data comes from an AVERAGE R\bRR\bRA\bA, the finest resolution of the
+ observed time series (one consolidated data point per primary data
+ point). The predicted (or smoothed) values are stored in the HWPREDICT
+ R\bRR\bRA\bA. The predicted deviations (think standard deviation) values are
+ stored in the DEVPREDICT R\bRR\bRA\bA. Finally, the FAILURES R\bRR\bRA\bA contains
+ indicators, with 1 denoting a potential failure.
+
+ All of the data is rescaled to bits (instead of Octets) by multiplying
+ by 8. The confidence bounds are computed by an offset of 2 deviations
+ both above and below the predicted values (the CDEFs upper and lower).
+ Vertical lines indicated potential failures are graphed via the TICK
+ graph element, which converts non-zero values in an R\bRR\bRA\bA into tick
+ marks. Here an axis-fraction argument of 1.0 means the tick marks span
+ the entire y-axis, and hence become vertical lines on the graph.
+
+ The choice of 2 deviations (a scaling factor) matches the default used
+ internally by the FAILURES R\bRR\bRA\bA. If the internal value is changed (see
+ rrdtune), this graphing command should be changed to be consistent.
+
+ _\bA _\bn_\bo_\bt_\be _\bo_\bn _\bd_\ba_\bt_\ba _\br_\be_\bd_\bu_\bc_\bt_\bi_\bo_\bn_\b:
+
+ The r\brr\brd\bdt\bto\boo\bol\bl _\bg_\br_\ba_\bp_\bh command is designed to plot data at a specified
+ temporal resolution, regardless of the actually resolution of the data
+ in the RRD file. This can present a problem for the specialized
+ consolidation functions which maintain a one-to-one mapping between
+ primary data points and consolidated data points. If a graph insists on
+ viewing the contents of these R\bRR\bRA\bAs\bs on a coarser temporal scale, the
+ _\bg_\br_\ba_\bp_\bh command tries to do something intelligent, but the confidence
+ bands and failures no longer have the same meaning and may be
+ misleading.
