(Fact-based Delta Trends continued)
The formula’s logic is as follows. If dollar amounts exist for both years, perform a normal %
change calculation (i.e., (Current-Previous)/Previous ). If an amount exists for the prior year
but not the following year, tag that as a delta of –100%. If no amount exists for the prior
year but one exists for the following year, tag that as a delta of +100%.
4) Add a final Computed Item to calculate the average delta across the entire range of years.
In our example, name it Avg_ Annual_Chg, and define its formula as:
( Chg_1993 + Chg_1994 + Chg_1995 + Chg_1996 + Chg_1997 +
Chg_1998 + Chg_1999 + Chg_2000 ) / 8
5) Select the Avg_Annual_Chg column, right-click on it and change the numeric display to be
0.00%.
6) With the Avg_ Annual_Chg column still selected, open the Spotlighter and define the
appropriate highlight definition. For example, say we wanted to highlight any average
change greater than 10%, you would define the Spotlighter as shown below:
Remember that Spotlighter values are defined in terms of the “raw” unformatted numbers.
Therefore, you need to enter the target value as 0.1 (the raw equivalent of 10%).
