4.5.3 Y-Axis Reference Lines
You may specify horizontal reference lines on the plots
produced by Presentation Graphics to indicate control limits
or objective values for the data element being plotted. For
example, if a two-hour objective has been set for Class B job
turnaround times, you might want to show this value as a
limit or objective in a report produced for the data element.
You may specify a maximum of 99 limits per plot.
Figure 4-7 shows a sample Y-Axis Reference Lines screen.

Figure 4-7. Y-Axis Reference Lines Screen
The parameters for the Y-Axis Reference Lines screen are
defined below:
Date: The date on which this limit should begin to
appear in the output plot. The dates need not
be week-ending or month-ending dates since
Presentation Graphics uses greater than or equal
logic to select the proper limits.
Value: The numeric value of the limit. Note that SAS
time formats are not supported for input and
must be specified as numeric fields. For
example, to place a reference line at the
two-hour vertical point on the Y-axis, specify
7200 for the Value parameter.
