Summary Variation
By default summary values are displayed “as is” in cells. To specify how summary values in a specific column correlate with summary values in the preceding column use the Summary Variation feature.
The Summary Variation feature is enabled via the SummaryVariation property of a data field. It gives you the capability to display:
The absolute and relative difference between summary values in adjacent columns that correspond to a specific data field.
Summary values as a percentage of row and column totals.
Refer to the SummaryVariation property description, to learn how summary values are calculated in variation and percentage modes.
