Presentation Graphics produce plots that depict the
forecasts generated using Univariate Modeling, Business
Element Forecasting, Multivariate Regression, and worksheets.
These plots show the historical data series, previous
forecasts, current forecasts, and confidence limits on each
forecasted point.
Figure 4-1 shows a sample printer graphics report for a TSO
response study. The title line of the report lists the
SYSID, ZONE, and report title that you specify on the
Presentation Graphics screen.
The body of the report displays the plot of the specified
data element. The Y-axis label shown in the plot is
specified for the Y-axis label control parameter. The values
on the Y-axis are scaled so that the numerical values shown
are less than 1,000. If the Y-axis values are scaled by the
program, then a scale block is generated at the base of the
Y-axis.
The scaling of the Y-Axis is not performed for variables
that represent time, such as the response variable, in this
plot. Time variables are recognized through the CA MICS
convention of ending the variable name with the characters
TM. For example, PGACPUTM represents the amount of MVS TCB
time accumulated for a performance group. These variables
are carried as SAS time values in the CA MICS database in
units of seconds.
Time variables are printed using a TIMEw.d format
(HH:MM:SS.DDD) for hours, minutes, seconds, and a decimal
portion of seconds. Scaling of time values presents a
readability problem, since hours and minutes do not
accumulate on a decimal basis. To aid in readability of time
values, the precision of the output format is designed to
float with the magnitude of the time value to be printed,
from a maximum of HHHHH:MM:SS. down to H:MM:SS.DDDD. This
allows printing of time values from 100 microseconds up to
10,000 hours with no loss of precision.
For printer plots, seven characters are used to denote the
points in the body of the plot:
* - historical observations
+ - current forecasted values
W - worksheet applied forecasts
P - previously forecasted values
U - the upper 95 percentile confidence limit
L - the lower 95 percentile confidence limit
= - a user-specified limit
| - line marking where history ends and future begins
A legend of these characters appears in the lower left corner
of the report. The example shown in Figure 4-1 includes both
a previous forecast and user-specified limits.
For color graphics plots, you can specify the symbols, line
types, and colors to use to plot the points in the body of
the plot. Figure 4-12 shows the Color Graphics Format
Parameters control screen that provides you with these
options and others.
The X-axis values correspond to the dates of the
observations. Depending on the timespan of the historical
observations and your CA MICS calendar, you will see one of
three X-axis formats: days, weeks, or months. For printer or
color graphics plots, all days, weeks, or months are shown on
a single plot.
Presentation Graphics automatically selects the proper report
format.
Presentation Graphics also enables you to specify up to six
60-character lines of information that are printed as
footnotes on both the printer and the color graphics plots.
