This tab is only available when Individual is selected in the Stack tab. It is used to define the Multiplier (scaling factor) and Offset in X and/or Y direction of the data plot.
Suppose the coordinates of original data plot are (X, Y). The coordinates (X', Y') of the stacked plot are defined as follow:
X' = Multiplier_X * X + Offset_X
Y' = Multiplier_Y * Y + Offset_Y
