Description
TRVReportColorChangerItem is a class of items in TRVReportTableItemInfo.BackgroundColorChangers.
If a report cell is linked to a color changer, this color changer changes the cell color and opacity according to a value associated with this cell.
Cells are shaded with gradations of two or three colors that correspond to minimum, midpoint, and maximum thresholds.
This class introduces new properties:
•OpacityBegin, OpacityMiddle, OpacityEnd – colors for defining a color scale
•ColorBegin, ColorMiddle, ColorEnd – the same for opacity
•PercentMiddle defines the midpoint.
The following properties are inherited:
•ValueString – expression to evaluate for cells.
•MinValue, MaxValue, AutoMinValue, AutoMaxValue – properties for calibration of the color scale
