STATISTICA BASIC Program 4Plot.stb

(nothing is guaranteed - use the program at your own risk)
Generates two XY-scatterplots. Corresponding points are marked with identical numbers in both plots.
STATISTICA's selection conditions are taken into account to enable the user to define subsets of interest.
As a consequence, the program requires STATISTICA 5.1 or higher to run (because STATISTICA 5 has no SelectionConditions() function). }
