+% SCATTERDATA Creates from the y-values of two input AOs an new AO(xydata)
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% DESCRIPTION: SCATTERDATA This method creates from the y-values of the
+%              input AOs a new AO with xydata. The y-values of the first
+%              input will be the x-values of the new AO and the y-values of
+%              the second AO will be the y-values of the new AO.
+%
+% CALL:        b = scatterData(a1, a2, pl)
+%
+% INPUTS:      aN   - input analysis objects (two)
+%              pl   - input parameter list
+%
+% OUTPUTS:     b    - output analysis object
+%
+% Possible actions:
