4.6.4.2 Control Parameters
Figures 4-17 and 4-18 show Presentation Graphics screens that
contain the control parameters that we used to produce the
quarterly management report.
Because multiple forecasts, each based on different data, are
maintained in the Capacity Planning database files, it is
easy to plot one of the previous forecasts using the forecast
date as the Previous forecast date parameter. If you do not
specify a value for this parameter, Presentations Graphics
automatically selects the most recent prior forecast for
plotting.
In this example, the current forecast is based on data
through June 1998 (and is thus the June 1998 forecast). The
most recent prior forecast is the March 1998 forecast (the
one based on data through March 1998). Leaving the previous
forecast parameter blank has the same result as the
specification shown in Figure 4-19 (that is, the specified
previous forecast, March 1998, is also the default previous
forecast).
