For the second shape, the jog statement tells the Jog Profiler to start
the Y axis at 3 units. At the summation point, this data is added to
the values from the other profilers to yield a Y-axis setpoint of +3:
For the third shape, the jog statement adjusts the starting point
again, this time changing the X axis to 5. The Y axis has not been
jogged so it stays at its previous value of +3:
For the fourth shape, the jog statement adjusts the starting point for
the Y axis back to 0. The X axis has not been jogged so it stays at its
previous value of +5:
Without offsets, coordinates for each shape would have to be
calculated (and debugged). Instead, one set of coordinates can be
reused and the starting point shifted through an offset.
